Can this be done with Arduinos and RFID modules? For example we have three rooms and a reception desk. Such as gym, pool and sauna. In front of each room there is a card reader (Arduino with RFID) and on the table is a card programmer (Arduino with RFID).
When someone comes to pay for example for a pool. Its card has to be programmed for example for 5 days. The card is valid from the first day from 9 AM until the last day to 5 PM and selected date. All informations are on card. Card reader near door knows he is reader for pool. He checks if it is card for pool or not and checks date and time. If everything is ok Arduino opens the door. A good example is access control to hotel rooms.
The readers and the card programmer are not interconnected, card reader is connected only to the power supply, card programmer only to the PC. The reader must only approve if the card is for that room and if the time and date period are good. Can this be done?
Visualization is required for the receptionist so he should not touch the code. Just select room, set date and time, put the card on the programmer and press OK, write or simething like that and the data is transmitted to RFID card.
