Who's responsible if a cleaner doesn't show up on site, or can't document their hours? Well, the fingers usually point at the owner or manager, and perhaps that's you. A few minutes here and there might not sound like much, but multiply it across a few hundred visits a month, and it's real money slipping through the cracks of a fixed-price contract.
So how do you actually know someone was there, and doing what they said they were doing? There are a few different ways to track it, each with its own trade-offs. This article walks through the pros and cons of the main time tracking methods, so you can decide what fits your business, so sit tight.
Summary
There are four main ways to track time and attendance on a cleaning site, each with a different trade-off:
- NFC tags — employee taps a physical tag to check in/out; hardest to fake, but needs hardware installed at every site
- GPS tracking — phone location is logged automatically; no extra hardware, but can register a cleaner as "on site" before work has actually started
- QR codes — employee scans a printed code; cheap and fast to set up, but a photographed code can be reused off-site
- Geofencing — clock-in triggers automatically inside a virtual boundary; no manual step needed, but crossing the boundary doesn't mean the job has begun
- None of the four confirms the cleaning was actually done to standard, that's a separate question for audits and inspections, worth its own look if proof of quality matters as much as proof of presence.
NFC Tags: How They Work
NFC tags work on the same principle as contactless card payment. A small NFC tag (or chip) is placed at the cleaning location, and the employee scans it with their phone to check in and check out.
Picture a cleaner arriving at a shopping centre before opening hours. They head to the stockroom to grab supplies, and tap a tag just at the entrance to the cleaning area, and only tap out once the job's actually done, not when they first walked through the door. The tag doesn't care how long they spent finding parking or where the mop bucket is kept, it only logs the moment of the scan.
GPS Tracking: How It Works
GPS tracking uses the same technology as everyday travel navigation. It pinpoints the cleaning location, and employees clock in and out when they're at that location, keeping track of both time and physical whereabouts.
Think of a cleaner who parks across the road because the car park's full, then walks over. The GPS might register them as "on site" the second they step off the pavement, well before they've picked up a mop. Or a large retail unit where the entrance and the stockroom are 200 metres apart, GPS might see enough movement to flag them as active even during a tea break in the van.
QR Codes: How They Work
This method links a QR code to a digital timesheet. The code is placed at the client's site, for example on the cleaning cart, and employees scan it to check in and out.
It works well until someone snaps a photo of the code on their first shift and keeps it on their phone. From then on, checking in doesn't require being anywhere near the actual site, just opening the camera roll.
GEO fencing: How They Work
Geofencing uses GPS to draw a virtual boundary around a work site, so employees can only clock in or out once they're physically inside that area.
An employee can enter the defined zone while still walking across a large site, finding parking, collecting keys, or making their way to the part of the building they're cleaning. Maybe that takes two minutes. Maybe eight. It depends entirely on the site.
A large hospital or office complex might have the entrance, the cleaning cupboard, and the actual work area spread across a boundary that's technically "inside" the whole time, so the clock starts the moment someone crosses the perimeter, not when the mop touches the floor.
A Quick Overview of the Time Tracking Methods
| Method | How It Works | Pros | Cons |
|---|---|---|---|
| NFC Tags | Employee scans a physical tag at the site to check in/out | Requires physical presence at the tag; tends to hold up better against manipulation; works offline | Requires tags to be installed and maintained at each site; doesn't work if a tag is damaged or missing |
| GPS Tracking | Employee's location is recorded when clocking in/out | No new hardware needed, most people already carry a GPS-enabled phone; tracks location in real time | Privacy concerns; drains battery; can be imprecise, allowing check-ins near, not inside, the site |
| QR Codes | Employee scans a code linked to a digital timesheet | Cheap and easy to set up; no app or scanner needed beyond the phone camera | A photographed code can be reused off-site; doesn't confirm actual presence |
| Geofencing | Virtual boundary around a site; employee can only clock in/out inside it | No physical tag needed; automatic based on location | Entering the zone doesn't mean work has started; timing can be off by minutes depending on site size |
Choosing the Right Time and Attendance System for Your Business
NFC, GPS, QR codes, geofencing, none of them is universally "right." What you're actually choosing between is where you're willing to lose a bit of accuracy, and where you're not.
If someone gaming the system worries you more than the setup effort, NFC is the one to look at, a cleaner has to stand at the tag to scan it, full stop. If you'd rather get something running today and worry less about a few minutes here or there, QR codes or geofencing get you there faster, just know a photographed code or a big site's awkward boundary can quietly work against you.
One thing none of them do: prove the job itself was done properly. A clock-in system tells you someone was there. Whether the toilets got cleaned to standard is a different question, and one for audits and inspections, not a tag or a tap.
If you're looking at time tracking as part of a wider move toward digital tools, Enhancing Efficiency Through Digitalisation in the Cleaning Industry covers the bigger picture, from IoT sensors to cleaning robots.
Need Some Help Choosing?
Picture this instead: a cleaner taps in at a hospital ward at 6am, offline because the basement has no signal, and the record still lands safely once their phone finds a connection again. No photos of QR codes floating around, no GPS battery drain, just a tap at the door.
That's what NFC-based time tracking looks like in practice with CleanManager.
