Clox writes every clock-in and clock-out into a tamper-evident ledger. Each punch is linked to the one before it and signed once signing is enabled, so the record can't be quietly edited or reordered after the fact. When a dispute, audit, workers' comp review, or chargeback comes up, you can hand over a record the other side can check on their own.
What it does and does not prove
It proves that the record of each punch hasn't been altered since it was recorded. Every punch carries its time. A clock-in also records whether a selfie was taken and, for workers the fence applies to, the GPS reading. It doesn't prove the GPS location is genuine. The location still comes from the worker's phone, the same as any GPS clock-in. Treat proof of presence as a way to keep a record from being changed later, not as a way to make a location impossible to fake.
Export it from Reports
Open Reports, set your date range, and open the Export menu. Under the Proof of presence group you get two downloads.
- Proof of Presence (PDF) is a printable, per-worker report of when each punch happened and the signature status of each record. A clock-in with a location also shows where it happened and the distance to the nearest worksite.
- Verifiable bundle (JSON) is a machine-readable file for one employee that another person can check independently. Because a bundle is a single chain of linked punches, it's available only when the report is narrowed to one worker.
Verify a record at getclox.com/verify
Anyone you give a bundle to can go to getclox.com/verify, paste it in, and check it. The verifier recomputes the record and confirms it hasn't been altered or reordered. Once Clox's signing key is in place, it also confirms that Clox signed it. Nothing pasted there is stored, and they don't need a Clox account.
