IVPay CupKey – NFC authorization and consumption tracking
IVPay CupKey is an add-on module for coffee machines and tabletop machines with credit input, developed for internal NFC card or key-fob use. It is not a bank card terminal, but a local authorization and settlement system.
- Usable with registered NFC cards and key fobs.
- Per-user counting, limits and suspension.
- Monthly export reports for company settlement.
- Perimeter LED feedback with blue, green and red status signals.
Operating principle
One use credit after NFC identification
The user touches the NFC card or key fob to the reader. If the ID is registered, active and has not reached its limit, the device sends an enabling impulse to the machine and records the use.
Customer feedback: the device uses a diffused perimeter LED strip to indicate status. Blue shows setup / Wi-Fi status, green indicates accepted or ready-to-use status, and red indicates rejected ID, limit or error.
- only an active, registered NFC identifier can authorize use,
- normal use increases the user’s consumption counter,
- the service card can be used for testing and is not counted as consumption,
- monthly consumption can be exported as a report.
