NodeMCU and RC522 and REST communication

Last time we made a device that reads RFID card and communicates with devices by broadcasting a message. This implies that on the same network a server must be. We can use another device to work as a proxy between reader and remote server but why? We can communicate directly with the server via HTTP requests and box can inform other devices about the result.
