How to verify a caregiver showed up
What “the caregiver showed up” rests on today
For most agencies and families, the answer that a visit happened comes from one of three places: a timesheet the aide fills in, a visit note written up afterward, or an electronic visit verification (EVV) clock-in. Two of those are authored by the person whose presence is the exact thing in question. The third is better, and required for Medicaid-funded care under the 21st Century Cures Act, but it answers a narrower question than people think. It confirms that a phone checked in at a time and a place. It does not, on its own, show the work.
That gap is small on a good day and enormous on a bad one. When care goes right, nobody looks at the record. It only gets pulled when something is wrong: a family two states away who senses their parent is being neglected, an agency facing a payer audit, a caregiver accused of skipping a visit she is certain she made. In every one of those moments, the same weakness surfaces. The record is a claim about a visit, and the visit is what is in dispute.
When the record said care, and the client was in jail
Consider a case the Missouri Attorney General’s office announced this year. A consumer-directed-care recipient arranged for his personal-care attendants to keep clocking in and out as though they were providing services while he was actually incarcerated in a city jail, so they could split the payments. Across the scheme, Medicaid was billed 131 times for care that could not have happened, for a loss of about $47,845 (Missouri Attorney General’s Office). The recipient and both attendants were convicted.
The clock-ins were not sloppy. They looked exactly like real ones, because a clock-in only has to look like a clock-in. Nothing in that kind of record ties the check-in to the client being present and the work being done, which is why it took a conviction, not a query, to sort out. A record built instead on a live photo, pinned to a place and a server-set time, would not on its own have proven the care happened. But it would have been far harder to fabricate than a costless clock-in, and it would have left something concrete to check, rather than a log that looked right until investigators pulled it apart. That is the difference between a record you file and a record you can show.
A clock-in is a claim about a location, not the visit
Be fair to EVV: it catches plenty, and a good EVV system is a real deterrent. The honest limit is what a check-in can and cannot say. It can say a phone reported itself at a coordinate at a time. It cannot say the aide walked in, that the client was home, or that the bath and the meal and the medication reminder actually happened. A check-in from the parking lot, from the car, or from a doorway looks identical to a check-in from the kitchen. Enforcement lawyers now treat EVV records as a fraud-detection frontier precisely because the check-in itself can be gamed (Rivkin Radler). None of this means EVV is worthless. It means EVV is a presence signal, and presence is not the same as the visit.
Change one input: capture the work instead of logging a claim
Keep everything else the same, and change one input. Instead of the aide reporting that the visit happened, have the work produce its own artifact at the moment it happens. That is what LockProof adds on top of an EVV system, not in place of it. At the visit, the aide gets a text link. The link opens a live camera, and the gallery is blocked, so an old photo, a stock image, or a picture from a different day cannot simply be attached. The photo has to come through the camera, right then. That does not make fakery impossible; someone determined could still point the camera at a screen or a printout. What it does is force the photo to be captured rather than chosen, which shuts the easy door of uploading one you did not just take. At capture, the record is stamped with a server-set time the aide cannot change, the GPS location at that moment, and a SHA-256 fingerprint over the image, the location, and the time. If anyone edits the record afterward, the fingerprint stops matching, so the change is detectable. That is a chain of custody, and it is the part a self-written note has never had.
Home care carries a duty a job site does not, so the guidance is deliberately narrow: photograph the task, never the patient. A made bed. A prepared meal on the counter. A signed care sheet. The front door on arrival. The point is to document the finished task, not to put a vulnerable person in front of a camera, and the record is stronger for it because it shows the result of the work rather than who it was done to.
Every way to verify a visit, and whether it holds in a dispute
| How you verify a visit | Holds in a dispute? | What it actually tells you |
|---|---|---|
| A timesheet or visit note | No — self-authored | What the aide wrote down, after the fact |
| An EVV clock-in | Presence signal, not the visit | A phone checked in at a time and place |
| A GPS ping alone | Location, not the work | Where a device reported it was |
| A photo texted from a personal phone | No — no sealed origin or time | That a picture exists, from any day |
| A sealed live photo of the task | Yes — dispute-ready | A live photo of the finished task, fixed to a time and place, tamper-evident after |
The pattern is the same one that shows up everywhere proof matters: anything authored by the party whose work is in question is a claim, and anything generated at the work, sealed so it cannot be quietly changed, is a record.
How to set up verifiable visit proof, step by step
None of this requires the aide to install an app or learn a system. The steps are short on purpose.
- Keep your EVV system for check-in and Medicaid billing. This sits alongside it; it is not a replacement and does not touch your compliance record.
- At the visit, the aide opens a text link. No download, no login, and the screens are available in English and Spanish.
- She takes a live photo of the completed task through the link. The gallery is blocked, so it has to be captured then and there, not chosen from a camera roll.
- The server stamps the record with its own time, the location at capture, and a SHA-256 fingerprint, then files it in the Evidence Vault by client and date.
- When a family, a payer, or an auditor asks, you hand over a shareable proof link they can open and check themselves, without an account.
What this proves, and what it does not
Be precise, because overclaiming is its own kind of dishonesty. A sealed visit record proves that the image was captured through the live camera, with gallery upload blocked, at a specific place and time, and that the record has not been altered since. It does not, on its own, prove that every task on the care plan was done, certify that the care was good, or guarantee that the scene in the photo is truthful; no capture can. And it is not a promise about how any court or payer will rule. What it gives you is narrower and more useful day to day: a dispute-ready, audit-ready record that turns “she says she came” into something both sides can look at. That protects the family, who gets a record of the visit instead of a promise. It protects the honest caregiver, who now has a record that backs her up when she is wrongly accused. And it protects the agency, which is no longer defending its billing with paperwork it wrote itself.

Common questions
How do you verify a caregiver actually showed up?
A clock-in or a timesheet records a claim, not the visit. To verify it, capture what the visit produced: a live photo of the completed task, taken through a link so an old picture cannot be attached, stamped with a server-set time and the location at capture. It will not prove every minute of care, but it turns "she says she came" into a record you can show instead of a note you have to trust.
Can EVV data be faked?
EVV confirms a phone checked in at a time and place, which catches a great deal. But a check-in can happen from a parking lot or a doorway without the work being done, and clock-ins have been entered for visits that never occurred. EVV is a presence signal; it is not a tamper-evident record of the task itself.
What happens if a family disputes whether a caregiver visited?
Without a verifiable record it is the family’s word against the aide’s, and neither can point to anything. A sealed photo of the completed task, with the time and location fixed at capture, gives both sides something concrete instead: the family sees a live photo of the work taken at that place and time and unaltered since, and an honest caregiver who was there has the record that backs her up.
How do you prove a caregiver did the tasks, not just showed up?
Presence and completion are different questions. A clock-in says someone arrived; it says nothing about the meal, the bath, or the medication reminder. A photo of the finished task — a made bed, a signed care sheet, a doorway on arrival — captured live and sealed, is the part that shows the finished task, not only the attendance.
Does verifying visits mean surveilling the caregiver?
No. There is nothing installed on the caregiver’s phone, so it cannot follow them. Location is captured only at the moment of the photo, never in the background and never between visits. It verifies the work, not the worker’s whereabouts, which is why honest aides tend to prefer it: the record is what backs them up.
