How does it work?:
The project is based on a client-server structure, where you have a single server (In Raspberry Pi 2) and customers are the doors.
Clients connect to wifi and establish communication through a REST API made with Django and Django REST framework that is in the server. As it is a very delicate service the idea is not to have the server on the Internet but in the local area.
The system creates a URL with the tag received by the reader and asks the server. Checks whether the tag has a user and if you have access permissions (as can be if the current monthly payments) to activate the relay which opens the door.
As a client there is a Raspberry has a relay that opens an electronic lock a reader NFC model RC522. Development version: ESP8266 with RC522(rfid/nfc) reader.
Support bots Telegram: When entering the first person into space in a group alerts Telegram which is open and equal to leave.
