# QR Code Creation Instructions for Stores

## How to create QR codes for different stores

For each store, you need to create a QR code that will contain a link to your application with the store parameter.

### URL format for QR codes:

```
http://your-domain.com/validator/?store=STORE_IDENTIFIER
```

### Example URLs for different stores:

**Store A:**
```
http://your-domain.com/validator/?store=A
```

**Store B:**
```
http://your-domain.com/validator/?store=B
```

**Store C:**
```
http://your-domain.com/validator/?store=C
```

### How to create QR codes:

1. **Online QR code generators:**
   - https://www.qr-code-generator.com/
   - https://qr.io/
   - https://www.qrcode-monkey.com/

2. **Creation steps:**
   - Open any of the generators
   - Select "URL" or "Website" type
   - Paste the corresponding URL for the store
   - Configure size and quality of QR code
   - Download the finished QR code

3. **Recommendations:**
   - Use high resolution for printing
   - Add caption under QR code (e.g., "Store A - Gift Card Scanner")
   - Test QR code before printing

### QR code placement:

- Print QR codes and place them in each store
- Recommended locations: checkout, information desk, entrance area
- Add instruction: "Scan QR code to verify gift cards"

### Result:

After scanning the QR code:
1. User will enter the application
2. All scan results will be saved to a separate file for this store
3. In the "View Scan Results" section, you can select a specific store to view statistics

### Log files:

A separate file will be created for each store:
- `scan_results_A.log` - for store A
- `scan_results_B.log` - for store B
- `scan_results_C.log` - for store C
- `scan_results_general.log` - for general results (if accessed without store parameter)
