The device is the small number in a fingerprint timeclock purchase. The costs that recur are enrolment time, the written notice and consent you owe every person, the supervisor minutes spent on rejected reads, and a deletion process somebody performs whenever a person leaves. None is large and all are routinely left out of the business case.
Enrolment, once and then continuously
The initial session covers everybody you have; after that every new starter needs enrolling before their first shift, which puts a step into onboarding that somebody has to own. In a workplace with high turnover this is not a one off project, it is a permanent small job, and forgetting it means a new starter standing at a reader that does not know them.
The exception queue
Rejected reads produce missing punches, missing punches produce supervisor overrides, and overrides that are not logged quietly reintroduce the problem the device was bought to remove. Count rejected reads per hundred punches during a pilot and again after three months, because a rate that stays high means the sensor does not suit the hands you actually employ.
Notices, retention and deletion
A written notice to each person, a lawful basis you can state, a retention schedule and evidence that a leaver's template was deleted. This is the real price list and it sits beside the hardware quote rather than inside it. It is also the part that an inspection or a complaint will ask about first.
Questions people ask about fingerprint timeclock
How long does enrolment take per person?
A few minutes when it works and considerably longer for the people whose fingers read poorly. Budget a session rather than fitting it around a shift.
Who owns enrolment for new starters?
Whoever runs onboarding, and it needs to be a named step. Unowned, it is the thing that gets missed.
Is there an ongoing licence?
Often, covering hosting, support and updates. Compare that against owning the device and the obligations outright.
