Time clock for maquiladoras: working-time record without devices
Short answer
A maquiladora can meet the electronic working-time record requirement with a QR code printed and posted on site, which each person scans with their phone. The law requires recording each person's start and end time; it does not require a wall-mounted time clock.
How work happens at a maquiladora
A maquiladora has line operators, technicians, materials handlers and supervisors, with fixed or rotating shifts and compressed workweeks. That creates three challenges for measuring working time:
- Compressed workweeks concentrate hours into a few days.
- Overtime is used to meet shipments.
- The workforce is large.
What the law requires of maquiladoras
Since the 2026 reform, the Federal Labor Law requires recording electronically the start and end time of each worker's workday (article 132, section XXXIV). Failing to do so is fined 250 to 5,000 UMA. The STPS will define who it applies to and what exceptions there will be. The details are in the reform guide.
Night shifts. A night shift lasts 7 hours at most, one less than a day shift. It helps if the record separates night hours from day hours.
Work peaks. Overtime has a weekly cap: 9 hours at double time in 2027, with a maximum of 4 per day on no more than 4 days, and never more than 12 total hours in a day.
Staff turnover. Each new person must clock in from their first day. With an app, registering them takes minutes.
How to record working time at a maquiladora
- Register the workplace and its shifts.
- Print the QR code and post it at the entrance or next to the register.
- Each person scans it on arrival, when leaving for a break and when going home.
- At the end of the day you review what does not add up and download the report whenever you need it.
Example. A scheme of four 12-hour days already reaches the daily maximum. There is no room left for overtime on those days.
Calculate your overtime
How to do the math by hand
Take a salary of $400 per day on a day shift. The ordinary hour is worth 400 ÷ 8 = $50. In 2027, with 11 overtime hours in the week, the first 9 are paid at double time (9 × $100 = $900) and the remaining 2 at triple time (2 × $150 = $300). Total: $1,200.
Common mistakes at a maquiladora
- Keeping attendance from memory or in a notebook.
- Recording the clock-in and forgetting the clock-out.
- Not separating night hours, which have a lower daily maximum.
- Covering peaks only with overtime, until exceeding the weekly cap.
- Leaving new people without a record during their first days.
What to check every day and every week
Every day.
- Who did not record their clock-in or clock-out.
- Shifts that went over their daily maximum.
- Departures later than planned.
Every week.
- Each person's overtime against the weekly cap.
- Days when someone came close to 12 hours.
- Rest days that were actually taken.
How much an overtime hour costs: example in pesos
Suppose a daily wage of $400 on a day shift. The ordinary hourly rate is $50. One overtime hour at double time costs $100 and one at triple time, $150. If a person works 9 overtime hours in a week in 2027, that is $900 extra.
It is an example to show the calculation, not a reference wage for the sector.

Frequently asked questions
Does a maquiladora need to buy a time clock?
No. The law requires an electronic record of working time, not a device. An app on a phone complies.
What options are there for recording working time?
An app on each person's phone, a shared tablet or a clock connected to a system. All three comply if they generate an electronic record per person, with a start and an end time.
How are shifts that cross midnight recorded?
Clock-in and clock-out are saved with their actual date and time, and the hours are added up even if the day changes.
Can I ask for more overtime in peak season?
The weekly cap is not extended for the season. It helps to plan relief staff.
Can someone work more than 12 hours in a day?
No. The sum of ordinary and overtime hours cannot exceed 12 hours per day.
