On-site check-in for service providers

Know who really came. And when.

A LetzCheck card at every site. Your providers scan it with their phone when they arrive and when they leave: the visit time is recorded on site, verifiable, impossible to make up afterwards.

The problem

The €1,000 invoice nobody can check

Your cleaning company, or the one looking after the grounds, bills you €1,000 this month. Including several night interventions, at a higher rate of course. Nobody saw them.

As proof, there is a visit notice slipped into the letterbox, a letter, a sheet signed all at once at the end of the month. Papers that can be filled in beforehand, from the van… or without ever coming.

Visit notice: dropped off any time, by anyone.
Letter, sign-in sheet: lost, unreadable, signed after the fact.
LetzCheck: the exact time, taken on site, at every visit.

With LetzCheck, every invoice line can be compared with the visits actually checked in. A line with no check-in? You know before you pay.

How it works

Three steps, nothing to install

We install a card or chip

A card at the entrance of each site for providers, a chip at each patrol checkpoint: plant room, car park, floor…

The provider scans

Providers hold their phone to the card when they arrive and leave. On patrols, employees do the same with the chip at each checkpoint.

You check

Every visit in your client area, hour by hour. One-click export to compare with invoices.

The NFC card

Placed at the entrance of each site. Providers hold their phone to it on arrival and departure, no app to install.

Employee patrols

The NFC chip

Ø 35 mm, 2 mm thick: discreet and durable, fixed at each checkpoint. The employee holds their phone to it, and the visit is logged.

A card that can’t be copied

Every NFC card and chip is protected by a rotating key. It can’t be copied or used remotely: to check in, you have to be there.

Who it’s for

For everyone who pays for visits

Residential buildings, offices, shops, industrial sites: whenever a provider works while you’re not there.

Employee patrols

Security guards, caretakers, maintenance teams: an NFC chip at each point of the route. Every visit is timestamped, day and night: you know whether the patrol was done, and in what order.

Cleaning

Arrival and departure time of every job, building by building.

Grounds and landscaping

Real visits, even when nobody is there to see them.

Maintenance and technicians

Lifts, heating, fire extinguishers: a record of every service visit.

Property managers

All your buildings and all your providers in a single table.
