Biometric attendance feels like the "serious" option — until you price the hardware, the installation, and the maintenance across every branch you might ever open. QR-based attendance delivers the same accountability using a device every student already carries: their phone.
QR vs Biometric, Side by Side
| Factor | QR Attendance | Biometric |
|---|---|---|
| Hardware cost | None — uses existing phones | Dedicated device per branch |
| New branch setup | Instant — print a QR code | Order and install new hardware |
| Maintenance | None | Ongoing device upkeep |
| Data collected | Check-in/out timestamp only | Fingerprint/face biometric data |
| Works during power outage | Yes, phone-based | No, device needs power |
| Accuracy with dirty/worn fingers | Not applicable | Can misread and fail |
| Scalability across branches | Instant, no per-branch cost | New hardware purchase every time |
| Student self-check-in support | Yes, via student app | Requires staff-operated device |
Librify's QR attendance lets students scan a center-specific code to check in and out, with results syncing instantly to the owner's dashboard — the same accountability biometric systems promise, without the hardware bill.
Which One Fits Your Library
Choose QR Attendance If...
You're a single-branch library or planning to add branches, want zero hardware investment, or your students already carry smartphones.
Biometric May Suit If...
You have a fixed single location with budget for hardware and specifically need physical presence verification beyond a phone scan.
