The RFID card contains an electronic circuit that when the tag is placed near or within the range of the RFID reader, the magnetic field produced by the reader activates the tag.
Next, the tag continuously sends data through radio pulses.
Finally, the data is received by the code reader and sent to a computer, microcontroller or other systems for processing.
These cards are printable and you can print your design on it using special printers.
