A time clock is a device or application employers use to record when employees start and end their shifts, and the total hours worked in between. Time clocks range from the old mechanical punch clock, where a paper card was stamped with a timestamp, to today’s digital versions: physical biometric scanners, mobile apps, and web-based punches. Whatever form it takes, a time clock’s job is the same: create an accurate, timestamped record that payroll can rely on.
Time clocks can be physical hardware installed at a fixed location, or software that runs on a phone, tablet, or browser. Both produce the same kind of record, a punch, but they fit different work setups. A warehouse with one entrance and a construction crew spread across job sites need different tools to solve the same problem.
Types of time clocks
Biometric time clocks
A biometric time clock verifies identity using a fingerprint or facial scan instead of a PIN, badge, or password. Since the person clocking in has to physically be there for the scan to match, this is one way employers address buddy punching, when one employee clocks in or out on behalf of another. Biometric clocks are usually installed as fixed hardware near a single entrance or work area, which makes them a common fit for warehouses, manufacturing floors, and restaurants with one central punch point.
If you’re considering biometric hardware, ask the vendor directly how the data is stored and for how long, and check whether your state has a biometric privacy law that applies. Illinois, for example, has its Biometric Information Privacy Act (BIPA), which places specific requirements on collecting and storing biometric data. Rules vary by state, so this is worth confirming with the vendor and, if you’re unsure, an employment attorney, rather than assuming one state’s rules apply everywhere.
Mobile and GPS time clocks
A mobile time clock runs as an app on an employee’s phone, letting them punch in and out from wherever they’re working. Many mobile clocks also record the phone’s location at the moment of the punch, and some add geofencing, a virtual boundary around a job site that only allows a punch from inside it. This combination is common for construction crews, field service technicians, and home health aides, anyone who doesn’t clock in from the same fixed location every day.
Tablet and kiosk time clocks
A kiosk time clock turns a shared tablet into a punch station for a break room, retail floor, or job site trailer. Employees typically identify themselves with a PIN, a badge scan, or a photo taken at the moment of the punch. This setup works well anywhere a group of employees shares one entry point and a dedicated device makes more sense than everyone needing their own phone or login.
Web and browser-based time clocks
A web-based time clock lets employees punch in through a browser on any computer, no dedicated hardware required. This is the simplest option for office-based or desk-based teams, and some setups restrict punches to a specific network or approved location so a remote employee can’t clock in from somewhere they’re not supposed to be working.
Time clock vs. time and attendance software
A time clock is the specific device or method someone uses to punch in and out. Time and attendance is the broader system that collects those punches along with absence tracking, PTO management, overtime rules, and compliance recordkeeping, then feeds all of it into payroll. A time clock is one input into a time and attendance system, not a replacement for one.
In practice, most software marketed as a “time clock app” today includes both: the punch mechanism and at least some of the attendance and reporting layered on top of it.
Choosing a time clock for your team
The right setup depends less on company size and more on where people actually work:
- A single office or fixed location usually does fine with a web-based clock or a shared kiosk, since everyone’s punching in from the same place anyway.
- A mobile or multi-site workforce, construction, field services, property management, generally needs a mobile app with GPS or geofencing, since there’s no single door to put a clock next to.
- A high-turnover or high-volume shift environment, warehouses, manufacturing, restaurants, benefits most from biometric verification at a fixed station, where buddy punching risk is highest and a shared PIN or badge is easy to pass around.
- A mixed workforce (office staff plus field or shift workers) often ends up running more than one clock-in method at once, which is fine as long as all of them feed into the same time and attendance system rather than creating separate records to reconcile by hand.
Physical hardware has one advantage a bare mobile app doesn’t: an employee has to be standing at the device to punch in, since the clock isn’t going anywhere. A mobile app can replicate that with geofencing turned on, but without it, a punch could technically come from anywhere. That’s the practical reason fixed locations, retail counters, factory floors, warehouse entrances, often stick with physical clocks even after everyone on staff has a smartphone: the hardware itself does the location check, no configuration required.
Cost, biometric privacy requirements in your state, and whether the clock needs to work offline at a job site with no signal are all worth confirming with a vendor before you commit to hardware specifically, since hardware is a harder decision to reverse than switching an app.
How a time clock connects to payroll
On its own, a time clock only produces punches, a timestamp for when someone started and stopped. Getting from that punch to a paycheck requires the punch data to reach payroll, either through a direct integration or by someone exporting a report and entering the totals manually. The time and attendance page covers this connection in more depth, including what to check for when comparing providers.
One platform for the clock and the paycheck
Fingercheck sells physical time clocks, including fingerprint and facial recognition models like the FACE ID 6, TA200+, and AC100C Fingerprint Time Clock, alongside the mobile time tracking app for teams that don’t need fixed hardware. Every clock connects to your network (ethernet or Wi-Fi, depending on the model) and is managed from inside the same Fingercheck platform that runs payroll, no separate system to set up or export from. Clocks work standalone if that’s all you need right now, or as the front end of the full payroll platform if you’re ready for both.

Track time your way, run payroll with ease
Fingercheck offers physical biometric clocks, mobile GPS punches, or both, all synced to the same account and flowing straight into payroll.
