QR-Based Product Standardization for Tile & Ceramic Retail

Project positioning

This project combined two connected systems:

a QR-based product identification and customer information standard for tile and ceramic products, and

a sales/accounting workflow platform for tile and ceramic retailers.

The first part was designed so that an ordinary customer could scan a QR code attached to a tile/ceramic product and immediately understand the product's technical and packaging characteristics without depending on a salesperson to interpret every field.

The second part digitized the commercial workflow from customer request through order preparation and delivery.

A broader standardization initiative was also planned around the QR structure so that tile and ceramic retailers in Tehran could use a common product-information format, allowing end customers to read and compare product specifications in a consistent way across different shops.

The correct portfolio framing is therefore:

A domain-specific QR product-information standard combined with sales, accounting, and order-fulfillment automation for the tile and ceramic retail sector.

It should not be presented merely as:

“a QR code app”

or:

“a tile shop website.”

Executive Summary

The tile and ceramic retail sector has a recurring usability problem:

A product is not defined only by its visual appearance.

The customer may need to understand:

dimensions,
product type,
grade,
product code,
carton capacity,
carton weight,
pallet configuration,
and the amount required for a specific installation area.

This information is often technical and difficult for an ordinary customer to interpret.

The project therefore introduced a QR-based product-information model.

Conceptually:

Physical Tile / Ceramic Product
              ↓
            QR Code
              ↓
   Structured Product Information
              ↓
 Customer Understands the Product
              ↓
 Area / Quantity Calculation
              ↓
      Sales / Order Process

Part A — QR Product Intelligence

The first subsystem focused on the product itself.

Each product was associated with a QR code that could expose or encode structured information about the product.

The purpose was to make technical product information understandable to ordinary buyers.

Product Information Model

A tile/ceramic product could include information such as:

Product
├── Company / Manufacturer
├── Product Name
├── Product Type
├── Width
├── Height
├── Product Code
├── Grade
├── Design
├── Color
├── Pieces / Coverage per Carton
├── Carton Weight
├── Cartons per Pallet
└── Calculation Data

Example From the Historical Interface

The provided mobile screenshot visibly shows fields such as:

Company
Type
Size
Design
Color

with a sample size:

80 × 80

and a product type shown as:

Super Polish

This demonstrates that the mobile-facing information model was structured around product attributes rather than generic free text.

QR as the Physical-to-Digital Bridge

The QR code acted as the bridge between the physical product and its digital description.

Physical Product
      ↓
    QR Code
      ↓
Digital Product Record

This made the product itself the entry point into the digital system.

Customer-Facing Objective

The design goal was not only to help store employees.

It was also intended to make the product understandable to ordinary customers.

The customer could scan the QR code and view the data directly.

This reduced dependence on:

handwritten labels,
incomplete verbal explanations,
inconsistent terminology,
seller-specific explanations.

Standardization Goal

A major strategic goal of the project was to create a common product-information structure that could be used by tile and ceramic retailers across Tehran.

The intended model was:

Retailer A
Retailer B
Retailer C
Retailer D
    ↓
Same QR Information Structure
    ↓
Customer Sees the Same Type of Data Everywhere

Why Standardization Matters

Without a shared structure:

Shop A → describes size one way
Shop B → describes packaging differently
Shop C → omits grade
Shop D → uses different terminology

With a shared structure:

Product
→ same core fields
→ same customer expectations
→ easier comparison

This makes the project closer to a retail information standard than a simple app.

Historical Claim Boundary

The confirmed project statement is:

A common QR-based information structure was created, and the plan was for tile and ceramic retailers in Tehran to use it so customers could understand product specifications consistently.

Do not overstate this as:

“All tile retailers in Tehran adopted the standard”

unless full adoption can later be documented.

QR Payload Characteristics

The historical scanner screenshot shows product information readable after scanning the code.

The visible content includes:

size,
product identifier/code,
product type,
grade,
carton-related information,
pallet-related information,
and a sample calculation.

This indicates that the QR representation was designed as a meaningful product-information payload rather than only a decorative code.

QR Payload Concept

Conceptually:

QR Payload
├── Product Identity
├── Technical Characteristics
├── Packaging Characteristics
└── Calculation Guidance

Product Identity

Typical identity fields:

Company
Product Code
Product Name / Type
Design
Color

Product Dimensions

For tiles and ceramics, dimensions are essential.

Example:

80 × 80 cm

Dimensions directly affect:

coverage,
packaging,
required quantity,
installation calculations.

Product Grade

The grade field is important because different quality grades may exist for the same nominal product family.

The QR standard therefore made grade visible as a structured field.

Packaging Intelligence

The project did not stop at product appearance.

It also described the packaging/logistics behavior of the product.

Important fields included:

pieces per carton,
square-meter coverage per carton,
carton weight,
cartons per pallet.

Carton Model

Conceptually:

Carton
├── Product
├── Pieces
├── Coverage
└── Weight

Pallet Model

Conceptually:

Pallet
├── Cartons
├── Total Coverage
└── Total Weight

Why Packaging Data Matters

For the retailer:

inventory,
warehousing,
delivery,
transport planning.

For the customer:

how many cartons to buy,
how many pallets may be needed,
approximate delivery scale.

Area Calculation Engine

One of the strongest features of the project was the domain-specific calculation engine.

The customer could provide the required installation area.

The system then calculated the required amount of product based on product dimensions and packaging rules.

Calculation Flow

Target Area
    ↓
Tile Coverage
    ↓
Required Tile Quantity
    ↓
Required Cartons
    ↓
Required Pallets
    ↓
Remaining / Partial Pallet

Example Logic

For example:

Required Area = 1000 m²

The system could determine:

How many tiles?
How many cartons?
How many full pallets?
How many additional cartons?

The scanner screenshot itself shows a worked example of this style of calculation.

Coverage Calculation

Conceptually:

Tile Area = Width × Height

Then:

Required Tiles = Target Area / Tile Area

After rounding to packaging constraints:

Required Cartons = ceil(Required Tiles / PiecesPerCarton)

Then:

Required Pallets = Required Cartons / CartonsPerPallet

The actual historical formula may also incorporate product-specific packaging rules.

Packaging-Aware Rounding

Retail products cannot usually be sold as arbitrary fractional packaging units.

Therefore the system needs to translate continuous area into discrete packaging.

Example:

Target Area
→ 781.25 theoretical cartons
→ 782 actual cartons

This type of rounding is a genuine business rule.

Waste / Safety Margin

The current project description confirms area-based calculation.

If a configurable installation waste margin existed historically, it should be documented separately.

A modern V2 could support:

5%
7%
10%
custom waste factor

depending on installation pattern.

Part B — Sales & Accounting Automation

The second subsystem addressed the retailer's operational workflow.

The objective was to digitize the process from customer request to product delivery.

Commercial Workflow

Conceptually:

Customer Requirement
        ↓
Product Selection
        ↓
Area Calculation
        ↓
Required Quantity
        ↓
Quotation
        ↓
Order
        ↓
Accounting
        ↓
Warehouse / Preparation
        ↓
Delivery

Order Lifecycle

The order becomes the central business object.

Order
├── Customer
├── Product
├── Required Area
├── Calculated Quantity
├── Cartons
├── Pallets
├── Price
├── Payment
├── Delivery Status
└── History

Customer Request

The process begins with the customer's actual need.

The system translates:

"I need tiles for X m²"

into:

Product + Quantity + Packaging + Commercial Order

Product Selection

Because products already had structured master data, the sales workflow could reuse:

dimensions,
packaging,
grade,
identifiers.

This avoids retyping product information during every sale.

Quotation

Once quantity is calculated, the system can generate the commercial basis for a quotation.

Conceptually:

Product
×
Required Quantity
×
Price
=
Quotation

Accounting

The second subsystem included accounting functionality for tile and ceramic stores.

The goal was to connect sales transactions to financial records rather than leaving accounting as a separate manual process.

Accounting Scope

A retail accounting workflow can include:

customer balance,
order amount,
payment,
outstanding amount,
invoice,
transaction history.

The exact historical screens should only be described where preserved.

Sales to Delivery

The system aimed to digitize the full commercial lifecycle:

Order Created
    ↓
Confirmed
    ↓
Financial Processing
    ↓
Prepared
    ↓
Delivered

Warehouse Interaction

Even if the historical inventory implementation details are incomplete, the product model naturally connects to inventory.

Each order consumes:

Cartons

and potentially:

Pallets

from available stock.

Product Master Data

The entire system depends on reliable product master data.

A conceptual modern model:

products
├── id
├── manufacturer_id
├── code
├── name
├── type
├── width
├── height
├── grade
├── design
├── color
├── pieces_per_carton
├── coverage_per_carton
├── carton_weight
└── cartons_per_pallet

QR Identity

Each product can be associated with:

product_qr
├── product_id
├── payload
├── version
└── active

QR Versioning

Because standards evolve, a modern implementation should include versioning.

Example:

QR Standard v1
QR Standard v2

This prevents future field changes from breaking old codes.

Canonical Product Schema

A shared retailer standard should define a canonical field structure.

Example:

manufacturer
product_code
product_type
dimensions
grade
design
color
carton_capacity
carton_weight
pallet_capacity

Interoperability

If many retailers use the same standard, the QR data should be independent of one specific shop.

This allows:

Manufacturer / Distributor
          ↓
Canonical QR Data
          ↓
Any Compatible Retailer
          ↓
Same Customer Interpretation

QR Data vs Retailer Data

A robust modern design should distinguish:

Product Standard Data

from:

Retailer-Specific Data

For example:

Standard Product Data

size,
grade,
packaging,
product code.

Retailer-Specific Data

price,
stock,
discount,
delivery date.

This separation improves reuse.

Public Customer View

The customer-facing interface should emphasize understandable information.

Example:

Company
Type
Size
Design
Color
Grade
Packaging
Coverage

rather than exposing internal database fields.

Retailer View

Retail employees may need more:

Stock
Purchase Cost
Selling Price
Supplier
Warehouse Location
Order History

Role Separation

Modern system roles could include:

Customer
Sales
Warehouse
Accounting
Manager
Administrator

Historical role names should be documented only if preserved.

Customer Role

Can:

scan QR,
view product information,
calculate required quantity.

Sales Role

Can:

create customer order,
calculate quantity,
prepare quotation,
check availability.

Warehouse Role

Can:

prepare goods,
confirm carton/pallet quantities,
mark dispatch.

Accounting Role

Can:

register payments,
confirm financial status,
issue accounting records.

Management Role

Can:

review sales,
review stock,
review financial reports,
configure product rules.

Inventory Model

For tile and ceramic retail, inventory may be represented at carton level.

Conceptually:

Stock
├── Product
├── Cartons Available
├── Pallets Available
└── Reserved Quantity

Reservation

When an order is confirmed:

Available Stock
      ↓
Reserve Required Cartons
      ↓
Prevent Double-Selling

A modern V2 should implement this transactionally.

Concurrency

If two sales employees sell the same product at the same time, the system should prevent inventory conflicts.

Use:

database transactions,
row locking,
reservation status.

Pricing

A product can have:

base price,
retailer price,
discount,
customer-specific price.

The historical pricing rules should be documented only where evidence exists.

Delivery Planning

Pallet calculations can support delivery planning.

Example:

Order
→ 782 Cartons
→ 20 Full Pallets
→ 2 Extra Cartons

This is operationally useful for transport.

Weight Calculation

Because carton weight is known:

Total Shipment Weight
=
Required Cartons × Carton Weight

This can support:

vehicle planning,
loading,
delivery estimation.

Logistics Value

The product standard therefore supports more than customer information.

It can also feed:

Sales
Inventory
Warehouse
Transport

QR Scanning Experience

The mobile screenshots show a dedicated product-information experience after scanning.

This demonstrates a simple and powerful interaction:

Scan
→ Understand
→ Calculate

Why This Matters for End Customers

Construction-material products are often difficult to compare.

A shared standard helps the customer answer:

What exactly is this product?
What size is it?
What grade is it?
How much area does one carton cover?
How many cartons do I need?
How many pallets will that be?

without requiring technical expertise.

Retail Transparency

The standard also improves retail transparency.

A customer can compare products using the same categories instead of relying on inconsistent descriptions.

Data Quality

A shared QR standard is only useful if product data is consistent.

A modern system should validate:

dimensions,
units,
product code,
grade,
carton coverage,
weight,
pallet quantity.

Unit Normalization

Important units may include:

cm
m²
kg
piece
carton
pallet

A canonical system should store units explicitly.

Validation Example

If:

80 × 80 cm

then tile area is:

0.64 m²

If a carton contains N pieces:

coverage_per_carton = N × 0.64

The system can validate whether stored coverage is consistent.

Calculation Engine Architecture

A modern implementation should isolate calculation rules from controllers/UI.

Example:

CoverageCalculationService
PackagingCalculationService
PalletCalculationService

Coverage Service

Input:

Product
Target Area

Output:

Required Pieces
Required Cartons
Required Pallets
Remainder

Calculation Result Object

CalculationResult
├── target_area
├── tile_area
├── pieces_required
├── cartons_required
├── full_pallets
└── extra_cartons

Rules Engine Potential

Different products may have different:

carton capacities,
pallet capacities,
packaging rules.

The system should therefore treat them as data-driven rules rather than hard-coded assumptions.

QR Generation

A modern workflow could be:

Product Created
      ↓
Validated
      ↓
QR Payload Generated
      ↓
QR Image Generated
      ↓
Printed / Attached

Label Printing

The physical deployment required QR codes to be printed and attached to products or packaging.

This is an important physical-digital integration point.

Printing Workflow

Product Master
     ↓
QR Generator
     ↓
Label Template
     ↓
Print
     ↓
Attach to Product / Package

Standard Label Layout

A common retailer standard can define:

QR placement,
human-readable product code,
size,
grade.

This helps even when scanning is unavailable.

Offline / Generic Scanner Readability

The historical scanner screenshot suggests that product information was designed to remain interpretable through a QR scanning workflow.

A robust standard should avoid making the QR useful only through one proprietary app.

Public Standard Philosophy

The strongest conceptual interpretation is:

The QR code should describe the product, not the retailer.

Retailer-specific functions can be layered on top.

This allows the standard to scale across many stores.

Multi-Retailer Architecture

A modern common platform could support:

Product Standard
      ↓
Retailer A
Retailer B
Retailer C

while each retailer maintains its own:

prices,
stock,
orders,
accounting.

Multi-Tenant V2

A modern implementation could be multi-tenant.

Tenant
├── Users
├── Stores
├── Prices
├── Inventory
├── Customers
└── Orders

The shared product master could be centralized.

Shared Master + Retailer Overlay

Shared Product Master
          +
Retailer-Specific Overlay
          ↓
Final Retail View

This is a strong modernization model.

Manufacturer Integration

A future version could allow manufacturers to maintain the canonical product data.

Retailers then consume it.

Manufacturer
     ↓
Product Master
     ↓
Retailers

This reduces inconsistent product descriptions.

Barcode / QR Identifier Strategy

A robust system should use stable unique identifiers.

Avoid encoding mutable data such as current price directly into permanent QR codes.

Use immutable product identity plus controlled data retrieval where appropriate.

Historical vs Modern QR Strategy

The historical project successfully exposed structured product information via QR.

A modern V2 could use:

QR = Stable Product Identifier

and retrieve current data from the platform.

This makes updates easier.

Security

Public QR scanning should expose only public product information.

Internal data such as:

purchase cost,
accounting data,
internal stock details

should remain authenticated.

Public / Internal Boundary

Public QR View
├── Product Specs
├── Packaging
└── Calculator

Internal System
├── Stock
├── Pricing Rules
├── Accounting
└── Orders

Accounting Integration

The commercial subsystem connects operational sales to financial records.

A clean modern flow:

Order
   ↓
Invoice
   ↓
Payment
   ↓
Accounting Transaction

Customer Balance

If credit sales are supported, the system can maintain:

Customer
├── Invoices
├── Payments
└── Balance

Do not claim historical credit-sales logic unless separately documented.

Order Status

A modern V2 could use statuses such as:

Draft
Quoted
Confirmed
Paid / Partially Paid
Prepared
Dispatched
Delivered
Cancelled

These are modernization examples.

Delivery Proof

A future version could record:

delivery date,
receiver,
signature,
shipment reference.

Reporting

Useful reports include:

Sales by Product
Sales by Size
Sales by Brand
Cartons Sold
Pallets Shipped
Inventory Remaining

Retail Analytics

Because product attributes are structured, the system can answer questions such as:

Which sizes sell most?
Which grades sell most?
Which manufacturers sell most?
Which products create the largest pallet volume?

Customer Analytics

If privacy rules allow, retailers can analyze:

recurring customers,
average order area,
order frequency.

Standard Adoption Strategy

For a multi-retailer standard, adoption should be gradual.

Conceptually:

Pilot Retailer
     ↓
Validate Fields
     ↓
Validate Customer Understanding
     ↓
More Retailers
     ↓
Common Standard

The historical project had the stated goal of broader Tehran retail use.

Governance of the Standard

A shared standard needs rules for:

field definitions,
versioning,
mandatory fields,
optional fields,
backward compatibility.

Example Mandatory Fields

Product Code
Manufacturer
Dimensions
Type
Grade
Carton Coverage
Carton Weight
Cartons per Pallet

Optional Fields

Design
Color
Marketing Name
Additional Notes

Standard Versioning Example

TCQR-1.0
TCQR-1.1
TCQR-2.0

This is a suggested modern governance model.

Backward Compatibility

Old printed QR codes may remain in stores for years.

Therefore the decoder should understand older schema versions.

Data Integrity

A QR standard should define:

required data types,
numeric precision,
unit conventions,
identifier uniqueness.

Example Validation Rules

width > 0
height > 0
carton_weight > 0
cartons_per_pallet > 0
product_code unique

Historical Evidence Strategy

The currently available images provide strong evidence for:

mobile product detail,
mobile inquiry/calculation form,
QR scan output with technical and packaging information.

Evidence Caption 1 — Product Detail

Customer-facing mobile product detail showing structured information such as company, type, size, design, and color.

Evidence Caption 2 — Inquiry / Calculation

Mobile inquiry interface where a product code and requested area can be submitted for quantity calculation.

Evidence Caption 3 — QR Payload

Historical QR scan showing structured tile/ceramic product specifications, packaging information, and an area-based calculation example.

Historical vs Modern Boundary

Confirmed Historical Capabilities / Facts

QR codes were printed and attached to tile/ceramic products.
Customers could scan them.
Product information included:
- identity/specifications,
- dimensions,
- type,
- product code,
- grade,
- carton capacity,
- carton weight,
- pallet placement/capacity.
An area-based calculation was provided.
A worked calculation example was included.
A second subsystem digitized tile/ceramic store sales and accounting.
The commercial flow covered customer order through delivery.
A common QR information structure was created.
The intended rollout was broader use among tile and ceramic retailers in Tehran so ordinary customers could understand specifications consistently.

Modern V2 Recommendations

QR schema versioning,
multi-tenant retailers,
manufacturer-owned product master,
API-based product lookup,
strict unit normalization,
inventory reservation,
transactional accounting,
modern mobile/web UI,
QR identifier instead of mutable embedded data.

What Not to Overclaim

Do not claim:

universal adoption by all Tehran retailers unless documented,
current mandatory industry-standard status,
national adoption,
specific accounting features not preserved in evidence,
manufacturer integration unless it existed historically.

Interview Story

Situation

Tile and ceramic products contain technical and packaging information that ordinary customers often find difficult to interpret consistently across different retailers.

At the same time, sales workflows in tile/ceramic shops could involve separate manual steps from customer request through accounting and delivery.

Task

The project needed to create a standard product-information model that customers could understand directly and also connect product information to the retailer's sales process.

Action

I designed a QR-based product-information structure covering product identity, dimensions, type, grade, carton information, weight, and pallet configuration.

I also implemented area-based calculation logic so the customer could enter the required installation area and receive calculated quantities in tiles/cartons/pallets.

A second subsystem digitized the commercial workflow from customer order through accounting and delivery.

The QR information model was intended to become a common format used across tile and ceramic retailers in Tehran.

Result

The project created a direct connection between:

Physical Product
→ Customer Information
→ Quantity Calculation
→ Sales
→ Fulfillment

and established a reusable foundation for standardized product communication across retailers.

Final Portfolio Statement

The strongest way to describe this project is not:

“I built a QR scanner for tiles.”

It is:

I designed a standardized QR-based product-information model for tile and ceramic retail, including technical specifications, packaging intelligence, and area-to-carton/pallet calculations, and connected it to a digital sales/accounting workflow from customer order through delivery.

The project demonstrates how a physical product can become a structured digital object and then drive the entire commercial workflow:

PHYSICAL PRODUCT
→ QR
→ STRUCTURED DATA
→ CUSTOMER UNDERSTANDING
→ QUANTITY CALCULATION
→ ORDER
→ ACCOUNTING
→ DELIVERY
