It is necessary to develop Arduino software to send requests when bringing an NFC card to the reader and when processing the received response (true/false) to open/close the door.
ESP-WROOM-32 Dev Module
NFC Reader PN532
You also need to save the database (~5000 UID with access status) to the device once a day.
The server part has already been developed and is ready for operation.
ESP 32 connects to a WIFI access point, if there is an Internet connection, it checks the access status by UID through the server. If there is no Internet connection, it checks the access status by UID with a locally unloaded database.
The local database is loaded once a day via a request to the server.
