I do is an equivalent of the laboratory equipment management system based on RFID technology, want to ask how to collect the RFID card number uploaded to the database, or uploaded to the web page, a management system that is more urgent, thank you!

Depends on the distance of the terminal and server you, if it is a collector used in the experiment and the server in the same debugging room can use a few such as zigbee such short distance wireless communication module; If it is actual application scenario, the collector and the server must be far apart, it is best to 4 g module for communication

CodePudding user response:

WIFI range 8266 can
Again a bit bigger LORA can
Wide field have to Internet, mobile unicom, yes, your online to find the corresponding module

Simpler to use serial transmission, do not need to increase the physical parts and software
The use of complex transmission, so need to increase so hardware and protocol stack
