  • Sessions expire after inactivity
  • Students automatically logged out

​
Best Practices

Explain to students: QR codes are like personal keys - don’t share them!
Create backups: Keep digital copies of all QR codes in secure location
Laminate high-use codes: Protects from wear and tear
Test before distributing: Verify each QR code works before giving to students
Display classroom master: Post all codes on wall for easy access during activities
Regular check-ins: Verify all students can still access their dashboards

​
Printing Tips

Optimal QR Code Sizes:
  • 2x2 inches: Individual cards (minimum readable size)
  • 3x3 inches: Standard printouts (recommended)
  • 5x5 inches: Classroom display
  • 8x8 inches: Large format for distance scanning
Larger is better for classroom wall displays!

​
Troubleshooting

Try these solutions:
  1. Improve lighting - QR codes need good light
  2. Clean camera lens - smudges prevent scanning
  3. Hold steady - keep camera still for 2-3 seconds
  4. Adjust distance - move closer or farther
  5. Try different app - some QR readers work better
  6. Check for damage - regenerate if code is torn/crinkled
This means:
  • Student may have been archived/deleted
  • QR code was regenerated and this is old code
  • Database connection issue
Solution:
  • Generate fresh QR code for student
  • Verify student is active in your roster
  • Contact support if persists
Very rare but possible:
  • Student scanning someone else’s code
  • QR codes got mixed up during distribution
Solution:
  • Verify student has correct code (name should match)
  • Regenerate all codes if widespread issue

​
Advanced: Direct URL Access

For older students or 1:1 device environments: Each student dashboard has a direct URL: 
https://classcents.com/student/dashboard/ABC123XYZ
Students can:
  • Bookmark this URL
  • Type it directly
  • Add to home screen on mobile devices
  • Share with parents for progress viewing
Keep nano IDs private! Anyone with the URL can access that student’s dashboard.

​
Parent Access

Parents can view student progress:
  1. Send QR code image to parents
  2. Parents scan with their phone
  3. They see same dashboard as student
  4. Great for parent-teacher conferences!
Encourage parents to check dashboards weekly - increases accountability and family engagement with classroom!
