What is Checkpoint scan?
A checkpoint scan is the record created when a security guard registers at a fixed patrol point (by tapping an NFC tag, scanning a QR code, or recording GPS at the location), proving the guard was physically present there at that time.
Also called: NFC checkpoint, QR checkpoint, patrol scan, guard tour checkpoint.
What are the different checkpoint methods?
| Method | How it works | Practical trade-off |
|---|---|---|
| NFC tag | Guard taps a phone against a tag fixed at the location | Hard to spoof remotely; needs tags installed and NFC-capable phones |
| QR code | Guard scans a printed code at the location | Cheapest to deploy; a photographed code can be scanned from elsewhere |
| GPS | Position is recorded when the guard marks the checkpoint | No hardware at all; accuracy degrades indoors and in dense urban sites |
| Mechanical key station | Guard inserts a key into a station on a handheld clock | Works with no phone or signal; data is only available once the device is downloaded |
