Approach
Open the lightweight check-in page and hold the phone near TapTime.
NFC attendance, made tangible
Tap in.
Tap out.
Clear records.
A simple physical checkpoint that turns one phone tap into a trustworthy attendance event—without surveillance, batteries, or kiosk training.

01 A physical point of presence
The core idea
Attendance should feel like arriving—not like being watched.
One natural gesture
From doorway to record
in under two seconds.
TapTime uses the familiar NFC gesture already built into modern phones. The web app identifies the employee, confirms the location, and records the event.
Tap
The NFC tag opens a signed workplace link. No device battery is needed.
Confirm
A clear success screen records check-in or check-out and shows the exact time.

Not a card.
A solid checkpoint.
A substantial two-piece case encloses the NFC module completely. The 17 mm body feels like a small appliance in the hand, while the removable rear gives access to the tag and mounting hardware.

MVP path
One entrance.
One team. Four weeks.
Validate the behavior before investing in custom hardware. Start with an NFC tag, this enclosure, and a small web flow.

Print the enclosure and write the pilot URL to the NFC tag.
- Week 2Team test
Enroll 5–10 employees and observe the entry flow.
- Weeks 3–4Measure & learn
Track successful taps, corrections, and payroll usefulness.
MVP honesty
A passive NFC tap proves that a phone reached the tag. It does not, by itself, prove who held the phone. Production should add authenticated employee accounts, rotating signed links, audit logs, and a dedicated reader where stronger assurance is required.
