NFC authorization
Managing cards and key fobs by unique ID.
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.

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.

Managing cards and key fobs by unique ID.
A perimeter LED light indicates device status using blue, green and red feedback.
Every authorized normal use can be recorded to a separate user.
A limit can be set per user, and a card can be suspended without deleting it.
CSV/TXT monthly report plus JSON data backup and restore.

CupKey is useful at locations where internal authorization, coffee benefit, departmental or per-user consumption tracking is needed instead of on-site payment.
Employee or guest consumption with internal card.
Monthly report by department, user or cost centre.
Service card use for maintenance without increasing consumption.
Managing limits, suspension and user status.
The device setup interface can be opened from a phone. New cards can be added, limits set, reports downloaded and backups managed.
After touching the new NFC identifier, it can be saved with a name or department.
Monthly consumption can be exported for settlement or administrative purposes.
The full database can be saved and restored in JSON format.
