At the gate or walking in: hardware clocking in JustLogin

At the gate or walking in: hardware clocking in JustLogin

Short answer: JustLogin offers two hardware clocking options. SafeClock is a wall-mounted tablet using facial recognition at a fixed entry point, with door access control-built in. rTAG uses Bluetooth to record the clock event as an employee arrives, with nothing to tap or queue for. SafeClock suits sites that need verified identity at the door; rTAG suits sites where speed at shift start matters most.

A biometric attendance system in Singapore uses facial recognition and biometric fingerprint scanning to track attendance, record working hours, and ensure accurate attendance tracking for employees.

Most attendance systems assume everyone carries a phone to their station and can use it the moment they arrive. It’s a reasonable assumption in an office. It falls apart almost everywhere else.

  • Factory floors where personal phones stay in lockers

  • Kitchens where hands are wet, full, or both

  • Warehouses where gloves make touchscreens useless

  • Sites running one shared device, with a queue in front of it at eight in the morning

For these workplaces, the clocking needs to live in the building rather than in someone’s pocket.

Biometric devices can record attendance, working hours, breaks, and overtime in real time, helping companies reduce manual processes and make more data-driven decisions.

What a queue at the terminal actually costs

A single device at a single entrance creates a bottleneck at precisely the busiest moment of the day. Everyone arrives inside the same ten minutes, and they arrive to find each other.

The costs are small individually and awkward in aggregate

  • People standing in line are technically late while they wait their turn

  • Punctual staff get recorded as late, which distorts both the data and the conversations that follow from it

  • Pressure builds to skip the terminal and sort it out later, which becomes a manual correction someone else has to make

  • Shift start times end up describing queue position rather than arrival

None of this is a discipline problem, though it often gets treated as one. The record should describe when people turn up, not how fast the line moved.

With fingerprint scanning, facial recognition, and instant access, a biometric attendance system can help employees clock in quickly while improving security, convenience, and attendance tracking.

SafeClock: the fixed entry point

SafeClock is a wall-mounted Android tablet that sits at the entrance and does rather more than record a time. 

  • Facial recognition clock-in and out – no cards to lose, no PINs to share

  • Door access control from the same device

  • Visitor detection, capturing and storing unrecognised faces at the entrance

  • Self-healing if the device drops offline

The identity piece is the part that matters most where clocking is shared. Cards get passed along, and PINs get borrowed, usually as a favour rather than a scheme, and by the time the hours look odd, the month has closed. A face is considerably harder to lend to a colleague.

It also collapses three systems into one. Most sites end up with a clocking device, a separate access system and a visitor book nobody has filled in properly since March – three things to maintain, and three sets of records that never quite agree.

Attendance data collected through biometric devices gives companies a clearer overview of employee working hours, shifts, breaks, absences, and overtime for better informed decisions.

rTAG: clocking in by walking in

rTAG takes the opposite approach. Rather than putting a device at the door, it removes the interaction entirely.

  • Bluetooth-based, recording the clock event as the employee comes into range

  • Nothing to tap, nothing to queue for, no screen to wake

  • Nothing for the employee to remember on arrival

The best version of a task you repeat twice a day, every working day, is the one that doesn’t require doing. rTAG is useful precisely where the queue problem bites hardest: shift starts that cluster, teams arriving together, sites where thirty seconds a person turns into a ten-minute bottleneck.

A biometric attendance system can connect attendance, door access, and payroll data, helping organisations streamline processes, maintain compliance, and improve control over employee working hours.

Which one suits which site

Manufacturing

  • SafeClock at the gate, where identity verification and door access matter together

  • rTAG where shift changes bring large groups through at once

Retail

  • SafeClock at the back-of-house entrance, one device per store

  • Facial recognition removes the shared-login habit that tends to develop across shifts

F&B

  • Hands are the constraint, not identity

  • rTAG avoids anyone touching a device mid-service or between covers

Offices with secure floors

  • SafeClock earns its place on access control as much as on clocking

  • Visitor detection adds a layer at reception without another system to run

Whatever mix a site runs, every clock event lands in the same attendance record. A company using both doesn’t end up with two datasets to reconcile. Also, our expert consultants can help you identify the best fit solution be it one or the other, or a mix. Speak to us today to find out more.

Health compliance features such as rigorous temperature scanning can work alongside biometric attendance, facial recognition, attendance data, and door access to create a more complete workplace security system.

Getting started

Both options work alongside mobile clocking rather than replacing it, so office teams can carry on as they are while the floor gets something that suits how they actually work.

For Singapore SMEs costing this out, attendance is part of JustLogin’s Productivity Solutions Grant package – worth checking eligibility before budgeting for hardware.
