Clock in on LINE, from the phone each person already has.

On arrival, the employee opens WorkCo from LINE and taps Check in. The phone sends its GPS position and the system checks it is inside the radius you set for that branch. Outside the radius, it says how many metres away the phone is and does not accept the check-in.

The time of the tap is measured against the shift you assigned that person that day, not against the shop's opening hour. Morning shift starts at nine and the tap is 09:10: ten minutes late. Afternoon shift starts at one and the tap is 09:10: early. The system already knows when each person was due.

Checking out is the same tap. The hours actually worked that day are recorded, and they are the same figures payroll uses. Nothing is retyped and nothing goes into Excel.

• Check in and out inside LINE. No app to install, no new password
• GPS checked inside a radius you set per branch. Default 200 metres, adjustable from 50 to 1,000
• A LINE reminder 5 minutes before the shift starts and before it ends, so people tap on time
• Check-in is on from the start. The GPS distance check applies once you set the branch's location, and an account that only sends schedules can hide the button

When someone taps in after their shift has started, the system records how many minutes late at that moment, stamps Late beside the name on the day's schedule, and adds it to the manager's notifications in WorkCo. Nobody has to trawl through a machine's log at the end of the month.

A grace period is set in each person's contract, for example the first 5 minutes not counted. The attendance report gathers every branch on one page: who was late, how often, how many minutes in total, and how many days each person worked this month.

• Minutes late shown against the person's name on the day's schedule
• Ten minutes after a shift starts, a LINE card to the owner can list who has checked in and who is missing
• Tomorrow's shift previewed in LINE at 20:00, so fewer people turn up for the wrong shift
• Reports export to a file for your accountant

A fingerprint scanner by the door is a second system you look after. It needs power and a network, and the day it fails nobody in the shop can clock in until a technician arrives. That month then has to be reconstructed by hand.

WorkCo uses the phone each person already carries. If one phone breaks, that is one person, not the whole shop. A new branch can clock in from day one with nothing to order, and staff out on deliveries or working away from the shop never have to come back to touch a machine.

• Nothing to buy, nothing to mount, no cabling
• No single point that stops the whole shop clocking in
• A new branch is live on day one

A manager opens WorkCo in LINE on a phone, or in any browser on a computer with the same LINE Login. The day's schedule shows who has checked in, who has not, who is late and who is on leave.

If someone forgets to check out, the shift is closed for them at its scheduled end, and they can send the time they really finished, with a reason. A time no longer than the shift is saved at once; a longer one goes to the manager to approve. A forgotten check-in is fixed by the manager in the hours at payroll time.

The position is read only when the employee taps in or out, to compare with the branch radius. WorkCo does not track location during the day, and stores no fingerprints or face images. What is stored and who can see it is set out on the security page.
