- This is a radio frequency ID card reader module that can read the ID card's serial number. It can help to design the intelligent access control system. When the module sensed ID card, it will convert the card number into a 9-digit hexadecimal number, each digit of which will be converted into ASCII code. Then it adds the starting byte and 5 other bytes, so a total of 15 bytes output to the serial port. You can convert it into a decimal number that is the serial number engraved on the ID card.
- Great for DIY.
