Using QR Codes
Connect physical items to digital records instantly via QR scanning
In This Tutorial
QR Code Overview
QR codes (Quick Response codes) are two-dimensional barcodes that can be quickly scanned using mobile devices. The Wavechrome Film Portal automatically generates unique QR codes for all trackable items, creating a bridge between your physical film inventory and the digital system.
Why QR Codes Matter
QR codes provide several benefits for radiochromic film management:
- Rapid Access: Instantly pull up digital records by scanning
- Error Reduction: Eliminate manual lookup and typing errors
- Workflow Efficiency: Speed up measurement and inventory checks
- Mobile Integration: Work seamlessly on phones and tablets
- Traceability: Create unambiguous physical-to-digital links
- Audit Trail: Automatic logging of when items are accessed
QR Code Technology
The platform uses secure QR codes that:
- Encode direct HTTPS URLs to item records
- Require authentication for sensitive data access
- Work with any standard QR scanner app
- Automatically detect from mobile device camera
- Are regeneratable if code becomes damaged

Pro Tip: Universal Scanning
Most modern smartphones have built-in QR code readers in the native camera app. No special application needed—just point and tap!
QR Codes for Different Entities
The system generates QR codes for multiple types of items, each serving different purposes in your workflow.
Batch QR Codes
Purpose: Link to entire film batch information
Use Case: Quickly access batch expiration date, all boxes in batch, film type specifications
Location: Typically on batch storage label or documentation
Box QR Codes
Purpose: Access complete box inventory and status
Use Case: Check available films, usage percentage, storage location, individual films within box
Location: Printed label attached to the physical box
Film QR Codes
Purpose: Track individual film details and measurements
Use Case: View film status, associated measurements, scan images, full history
Location: Small label on individual film or packaging
Measurement QR Codes
Purpose: Access measurement results and data
Use Case: Share measurement data with colleagues, external review, quick access to results
Location: Can be generated for reports or documentation

Generating and Downloading QR Codes
The platform automatically generates QR codes, but you need to download and print them for physical use.
Automatic Generation
QR codes are automatically created when you:
- Create a new batch
- Create a new box
- Create a new film
- Record a new measurement
Downloading QR Codes
Steps to Download:
- Open the detail page for the item (batch, box, film, etc.)
- Look for the QR Code section on the page
- Click "Download QR Code" button
- Image saves to your Downloads folder as PNG file
- File is named descriptively (e.g., "BOX-001-QR.png")
QR Code Image Specifications
- Format: PNG image (lossless)
- Size: 300 x 300 pixels
- Resolution: 300 DPI (print-ready)
- Color: Black and white for optimal scanning
- File Size: ~2-3 KB
Bulk Download
For multiple items, you can:
- Download individual QR codes one at a time
- Use "Generate QR Report" to create a PDF with multiple codes (Premium feature)
- Export batch data with embedded QR codes

Scanning QR Codes
Scanning is the quickest way to access item information from anywhere in your facility.
Mobile Scanning Process
How to Scan:
- Open your phone's camera app (iPhone, Android, or any phone)
- Point the camera at the QR code
- A notification banner appears (native functionality)
- Tap the notification to open the link
- Your browser loads the item's digital record
- You're logged in automatically if previously authenticated
Alternative Scanning
If your phone's native camera doesn't recognize QR codes:
- Download a free QR code scanner app from your app store
- Use the dedicated app to scan codes
- The app will automatically detect the URL and open it
Web Scanning
On desktop computers or laptops:
- Visit the QR scanner tool on the platform
- Use your webcam to scan codes
- Or manually enter the code ID if printing is unclear
Troubleshooting Scans
- Code not recognized: Ensure good lighting and stable camera position
- Partial scan: Keep code in center of frame for 2-3 seconds
- Damaged code: Regenerate a new QR code from the detail page
- Wrong item: Verify you're scanning the correct code label

Physical Management and Labeling
Proper physical handling of QR code labels ensures they remain scannable and useful throughout the film's lifecycle.
Printing QR Codes
When printing QR codes:
- Paper Type: Standard 8.5" x 11" laser or inkjet paper
- Print Quality: Use standard or high-quality setting
- Size: Print at least 2" x 2" (larger codes are easier to scan)
- Recommended: Print 4 codes per page or 2" x 2" label sheets
Label Attachment
Best practices for attaching labels to items:
Labeling Guidelines:
- Use adhesive label stock or clear label tape
- Clean the surface before applying (dry and dust-free)
- Attach in a visible, easily accessible location
- For boxes: Attach on front or top surface
- For films: Attach on edge or corner (not on viewing surface)
- Ensure code is not folded, wrinkled, or covered
- Leave at least 1/4" white space around the code
Protection and Durability
To maintain QR code functionality:
- Lamination: Laminate labels to protect from moisture and wear
- Temperature: Store in cool, dry conditions (like films)
- UV Protection: Protect from prolonged direct sunlight
- Handling: Avoid excessive bending or creasing
- Cleaning: Clean gently with dry cloth if dusty

Tip: Backup Identifiers
Always include the human-readable item ID (BOX-001, FILM-12345, etc.) printed alongside the QR code. This provides a fallback if the QR code becomes unreadable.
Real-World Workflow Example
Here's how QR codes streamline a typical film measurement workflow:
Complete Workflow Scenario
Step 1: Receiving Films
New batch arrives. Technician:
- Registers batch in system
- Creates boxes for this batch
- Downloads and prints QR codes
- Attaches codes to physical boxes
Step 2: Storage and Inventory
Films are stored. Manager:
- Needs to verify storage location
- Uses phone to scan box QR code
- Instantly sees: batch info, expiration date, storage location, films available
- Confirms inventory is correct
Step 3: Quality Assurance Check
Time for QA measurement. Technician:
- Scans box QR code to locate storage area
- Retrieves box and removes an available film
- Scans film QR code
- System shows film is available and ready to use
- Proceeds with measurement
Step 4: Measurement Recording
After measurement. Technician:
- Returns film to box
- Scans QR code when recording measurement
- System auto-selects the correct film
- Measurement is automatically linked to film
- Film status updates to "Used"
Step 5: Result Verification
Later, reviewer needs to check results. They:
- Scan the measurement QR code from a report
- Instantly access all measurement data
- Can scan associated film QR to see its history
- Complete audit trail is available

Pro Tip: Workflow Efficiency
A typical measurement process with QR codes takes 70% less time compared to manual lookup. That adds up to significant time savings across your organization!
Summary
QR codes are a powerful tool that connects your physical film inventory to digital records instantly. The platform automatically generates codes for all items. Download, print, and attach them to boxes and films. Use your phone's camera to scan codes and instantly access item information. With proper labeling and protection, QR codes will serve your organization reliably for years, dramatically improving workflow efficiency and reducing errors.
