An employee punch clock records when workers start and stop work, using paper time cards or electronic punches. For U.S. federal Fair Labor Standards Act (FLSA) recordkeeping, employers generally do not have to use a physical clock: they may choose any method that produces complete and accurate records. The right setup depends on the worksite, how employees clock in, and how the business calculates and exports time.
What is an employee punch clock?
A punch clock is a timekeeping device employees use to record work times. Traditional models stamp entries on paper time cards; electronic models record punches digitally and may offer calculations or data transfer. A physical clock is one way to collect time, not a complete payroll or compliance system by itself.
Do employees have to punch a time clock?
Under the U.S. federal FLSA guidance cited here, employees entitled to overtime pay are not required to punch a time clock. The Department of Labor says, “Employers may use any timekeeping method they choose,” provided the method keeps complete and accurate records. Employers may use a time clock, a timekeeper, or employee-maintained records. See the U.S. Department of Labor’s Small Entity Compliance Guide and Fact Sheet #21.

Fixed schedules and flexible hours
For employees on a stable fixed schedule, the DOL guide says an employer may keep the schedule and note exceptions when actual hours differ. For flexible schedules, it describes recording daily totals instead of requiring a punch for every start and stop, as long as the hours are accurately recorded. A schedule is not a substitute for recording actual hours when employees work different hours.

Work time is not the same as a punch
A clock entry does not automatically determine what time is compensable. The employer must count hours actually worked: an early or late punch without work does not itself establish work time, but work performed must be counted. Rounding is acceptable only when, over time, it does not result in failing to count all hours worked. The DOL explains this in its FLSA Hours Worked Advisor.
Automated timekeeping does not shift that responsibility. A 2024 Wage and Hour Division bulletin says employers remain responsible for accurate records and paying for all hours worked even when software uses AI to predict or prepopulate time entries. See Field Assistance Bulletin No. 2024-1.

What records should an employer keep?
For covered nonexempt workers, the DOL’s Fact Sheet #21 lists identifying information and work and pay details such as hours worked each day and workweek; pay basis and regular rate; straight-time and overtime earnings; additions or deductions; total wages; and payment date and pay period. It gives general federal retention periods of at least three years for payroll records and two years for records used to calculate wages, including time cards and work schedules. See the DOL recordkeeping fact sheet.
These are federal FLSA guidelines, not a summary of every state or local rule. Other requirements may apply, including rules concerning biometric data, labor agreements, or particular industries. Employers should check the requirements that apply where their employees work.

Which kind of time clock fits your workplace?
Choose based on the workflow the clock must support—not simply whether it is described as “electronic.” These categories are comparison points, not product endorsements.
| Option | Often useful for | What to check |
|---|---|---|
| Traditional punch-card clock | A fixed worksite with a straightforward paper-card process | Card format, print mechanism, employee capacity, whether it calculates totals, and ongoing availability of compatible cards and ribbons. Acroprint lists punch-card models including the ATR480 and M150MC4; Lathem lists traditional models such as the 1600E, 700E, and 400E. Check current manufacturer details at Acroprint and Lathem. |
| Electronic or connected employee clock | Businesses that want digital punches, calculations, or time-data transfer | Whether employees use a PIN, badge, or biometric input; what happens offline; report and payroll-export options; network requirements; employee capacity; and any ongoing subscription or support costs. Confirm each feature for the exact model. |
| Software, web, or mobile timekeeping | Distributed teams or workplaces that do not need a shared physical terminal | Whether the method captures actual hours, supports edits and approvals, and can produce complete, accurate records. The DOL guidance permits methods other than a physical clock, subject to those recordkeeping requirements. |
How to choose and roll out a clock
- Map the work pattern. Decide whether employees report to one site, move between locations, work remotely, or follow flexible schedules.
- Choose the punch method. Compare paper cards, PINs, badges, biometrics, and software entry against how employees will actually record time. If considering biometrics, check applicable privacy rules before rollout.
- Check the full workflow. Confirm employee capacity, offline behavior, calculations, reports, payroll export or integration, and any network or subscription requirements for the specific model.
- Confirm supplies and documentation. For a paper clock, verify the exact card and ribbon compatibility and continuing availability. For a digital system, review current product documentation and how corrections are made.
- Set procedures for exceptions. Explain how workers report missed punches, schedule changes, and time worked outside scheduled hours. Make sure edits preserve an accurate record rather than erasing work time.
- Check records and retention. Ensure the overall process captures required work and pay information and retains records for applicable federal, state, and local periods.
Manufacturer catalogs establish the features they market, not independent performance or legal compliance. No clock described here has been independently tested; confirm current model documentation and local requirements before buying or deploying one.
