Ukončen K zaplacení v momentě doručení

Hi. I'm running a cafe.

I plan to have a system that controls prepaid items.

Ie: customer buys 10pcs product A, 5pcs B, 20pcs C, but will only redeem them progressively.

Each customer will be given a contactless card (nfc or mifare), each time an order is made, the card will be used to "pay/redeem" for items.

Customers can check their credits at a checkpoint.

The system can either be Android(smart phone), RaspberryPi, ESP32, Arduino based. Working offline.

Hardwares that I have:

Esp32 , esp8266

Rpi

NFC reader, cards

.Etc

Arduino Microcontroller Elektronika Android Programování v C
