Electronic working-time record for electronics and cell phone stores

Short answer

A cell phone store 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 cell phone store

A cell phone store has salespeople, repair technicians and cashiers, with mall hours, kiosks and small shops. That creates three challenges for measuring working time:

  • Mall kiosks have nowhere to install a device.
  • One salesperson covers the whole shift alone.
  • There are many small points of sale.

What the law requires of electronics and cell phone stores

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.

Sundays. Someone who works on a Sunday is entitled to a premium of at least 25% of one day's wage. The record tells you which Sundays each person worked.

Multiple locations. Each place needs its own clock-in point. With a QR code, that is one printed sheet per location.

How to record working time at a cell phone store

  1. Register the workplace and its shifts.
  2. Print the QR code and post it at the entrance or next to the register.
  3. Each person scans it on arrival, when leaving for a break and when going home.
  4. At the end of the day you review what does not add up and download the report whenever you need it.

Example. At a mall kiosk, the QR code is stuck inside the counter. It needs no power or fixed internet.

25% of one day's salary for each Sunday worked.

Legal minimum: 25% (article 71 of the LFT).

How to do the math by hand

With $400 per day, the premium for one Sunday is 400 × 25% = $100. If the person worked all four Sundays of the month, it is $400.

Common mistakes at a cell phone store

  • Keeping attendance from memory or in a notebook.
  • Recording the clock-in and forgetting the clock-out.
  • Not identifying which Sundays each person worked.
  • Using a different control at each location.

What to check every day and every week

Every day.

  • Who did not record their clock-in or clock-out.
  • Departures later than planned.

Every week.

  • Each person's overtime against the weekly cap.
  • Sundays worked, for the Sunday premium.
  • Rest days that were actually taken.

How much an overtime hour costs: example in pesos

Suppose a daily wage of $350 on a day shift. The ordinary hourly rate is $43.75. One overtime hour at double time costs $87.50 and one at triple time, $131.25. If a person works 9 overtime hours in a week in 2027, that is $787.50 extra.

It is an example to show the calculation, not a reference wage for the sector.

Frequently asked questions

Does a cell phone store 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 do I know how much Sunday premium to pay?

With the record you know which Sundays each person worked; the premium is at least 25% of one day's wage.

What happens if someone works at two locations?

Use the same account. Each record is linked to the place where it was made.

Who monitors compliance?

The Ministry of Labor and Social Welfare, through inspections.
