QR Attendance vs Biometric: What's Right for Your Library

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.

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.
