Mobile and GPS attendance for field and remote staff in Sri Lanka

When mobile check-in beats a fixed device

A fingerprint or face terminal needs a fixed door, mains power and a network point, and it only knows who is standing in front of it. That works for an office or a factory gate; it does not work for a sales rep visiting five clients a day, a delivery rider, a maintenance technician on a job site, or a remote employee with no office to walk into. For that workforce, the practical alternative is a check-in and check-out button in a phone app, with the location captured at the moment of the punch so the record shows roughly where the person was, not just when.

Geofencing basics

Geofencing means the app only accepts a check-in when the phone’s location falls inside a boundary drawn around a work site — a client office, a warehouse, a delivery zone — so a punch cannot be recorded from somewhere else. It is the standard way mobile attendance systems limit check-ins to where work is actually meant to happen, alongside plain location capture that records where a punch happened without restricting it. The Humanised employee app supports configurable geofencing: you set a boundary around each work site, and the app records and verifies location at check-in and check-out against it.

Fraud controls to look for

A phone check-in is easier to fake than a fingerprint, so the controls that matter are about the phone and the location, not the punch itself.

• Location capture at the moment of check-in and check-out, so a punch carries a record of where it happened.
• A boundary or geofence around the work site, where supported, so a check-in outside it is rejected or flagged.
• A photo or selfie at check-in on higher-risk roles, where the app supports it.
• One device per employee login, so a punch cannot be made from a colleague’s phone.
• A manager review step for check-ins outside the expected zone or time, rather than automatic acceptance.
• An audit trail an employer can produce if a punch is disputed.

This list describes what a mobile attendance system generally needs. Humanised covers location capture and configurable geofencing in the employee app; ask any vendor, including us, to show each control working in a demo before you write it into an attendance policy.

How a mobile punch becomes overtime and no-pay

A GPS check-in has to be reconciled against the employee’s shift the same way a fingerprint punch is, under the same Shop and Office Employees Act rules: normal hours of 8 a day and 45 a week, overtime capped at 12 hours a week and paid at not less than 1.5× the hourly rate, with the hourly rate for monthly-paid staff calculated as the monthly salary ÷ 240 (Regulation 8). See the Shop and Office Act guide and the leave entitlements guide, both reviewed 3 September 2026, for the full rules. An unexplained gap between a scheduled shift and a mobile check-in becomes a no-pay day the same way a missed fingerprint punch does; the software, not the check-in method, applies the rule. The overtime calculator works the calculation through with numbers.

Which industries use mobile GPS attendance

Sri Lankan employers most likely to need it are those with staff who are not at a desk or a factory gate for most of the working day: field sales and merchandising teams, delivery and logistics riders, maintenance and installation technicians, security staff rotating between sites, and companies running a hybrid or remote-first office policy. This is a description of the kind of workforce the method suits, not a list of named customers. Many of these employers still keep a fingerprint or face terminal at the head office for administrative staff, and run the two attendance methods side by side on the same payroll.

What a mobile attendance record needs to show

The Shop and Office Employees Act requires a record of hours actually worked each day, including overtime, whichever way the punch was captured — see the record-keeping duties in the Shop and Office Act guide. For a mobile punch that means the record should show the time of check-in and check-out, the location captured at that moment, and which shift it was measured against, so the same file can be produced if the Labour Department or a Labour Tribunal asks for it. A screenshot of an app is not a record; the underlying log the software keeps is. Keep this in mind when comparing vendors: ask whether the export includes the location field, not only the time.

Mobile GPS vs a biometric terminal

Buying and rollout checklist

• Confirm whether check-in needs to be restricted to a geofenced site or only needs location recorded — ask the vendor which the app supports today.
• Decide the policy for staff with patchy mobile data or GPS signal indoors, and how a manager overrides a failed check-in.
• Tell staff in writing what location data is captured, when, and for how long it is kept.
• Check the app works on both iOS and Android if your team is mixed.
• Confirm the mobile punch reaches the same attendance and payroll engine as any fingerprint or face terminal at the office, so a mixed workforce is not split across two systems.
• Test one full pay cycle with a small group before rolling out to the whole field team.
