Most safety apps capture attendance with an on-screen signature or a typed name. That is a genuine improvement over paper on retrieval and legibility. It is not an improvement on the thing that decides a contested case: whether the record establishes that the named worker was actually there.
Documentation records that something was entered. Verification produces evidence that something occurred. A signature — wet or digital — is documentation. It captures an assertion. Verification captures a fact independent of the assertion: a live photograph of the person, coordinates placing them inside the geofence, and a timestamp sealed at capture.
The practical weakness of signature capture is that one device circulates. A foreman holding an iPad can collect fifteen signatures in ninety seconds, and nothing in the record distinguishes fifteen workers signing from one person signing fifteen times. This is the single most common way digital attendance records fail under scrutiny.
Requiring a photo at the moment of check-in ties the record to a person rather than to a device. Combined with GPS, it answers who and where together. Neither is inferable from a signature.
A record that can be edited after the fact is weaker than one that cannot. Arkvos hashes each check-in with SHA-256 at capture. If anything in the record changes later, the hash no longer matches — which means the record's integrity is checkable by a third party rather than asserted by you.
For internal training tracking, for programs with no external audit exposure, and for organizations where nobody will ever contest the record, signature capture is adequate and usually cheaper. The distinction only pays for itself when a record is challenged.
It proves a name was entered on a device. It does not establish that the named person was physically present, because anyone holding the device can sign. Where the record may be contested, a live photo plus GPS inside a geofence is materially stronger.
Documentation records that something was entered — a name, a signature, a form submission. Verification produces evidence that something occurred, generated independently of the person making the claim. A photo taken at check-in with GPS coordinates is verification; a signature is documentation.
With signature-based systems, generally yes, and the record will not show it. Requiring a live photo per worker at check-in is what prevents it, because each record is tied to a face rather than to a device.
A cryptographic fingerprint calculated from the record's contents at the moment of capture. If the record is altered afterward, the recalculated hash no longer matches the stored one, so tampering is detectable rather than invisible.
