Our Online Store have the new products: RFID antenna board. Currently it can work with JC10M24R and JCOP4 card chips.
Compared with normal cards, the antenna board module has a smaller size and fixed holes, which is easy to integrate in the IOT(Internet Of Things) project.

RFID Reader Usage Based on Arduino Board

Post by JavaCardOS » Tue Jun 15, 2021 11:35 pm

RFID Reader Kit developed by JavaCardOS Technologies is implemented based on Arduino hardware platform and this kit provides RFID card reader's functions.
You can use this development kit by the following operation:
1.Prepare 2.HardWare details and Wiring
  1. The digital pin of RFID Board
    2. The Digital pin of Arduino Board,
    The below two types Arduino Board we are all supports,
    * * * * * * * * * * * * The default types Arduino Board * * * * * * * * * * * *

    (3)The Wiring index table of RFID Expansion Board and Arduino Board
    [*GND <---> GND]
    [* VCC <---> 5V (or Vin)]
    [*Tx <---> digital pin 3]
    [*ANT+ <---> The Red Antenna Coil]
    [*ANT- <---> The Black Antenna Coil]

    (4)The wiring diagram is as follows:
    Or using the other Arduino Board with the Keyfob ID Card.
3.Upload project to the arduino board
  1. Download the source code(RFID_125K_Reader.zip in the attachment)
    2. Click arduino.exe to open the Arduino IDE tool, and select 'rfid_reader.ino' file to open the project
    3. Click the Verify button to Verify/Compile project.
    4. Select 'Tools'->'Port'->'COMx', the 'x' is the serial port number connected to the Arduino development board
    5. Click Upload button to upload the code to the Arduino development board
    6. Put the RFID card to the antenna oil, the serial number of the RFID card will appear in the Serial Monitor Window.
  • 1. Put different RFID cards on the coil, the serial monitor can monitor and print the ID number of the card
    2. If put the same RFID card on the coil, there will be no response from the serial monitor window.
    3. The number on Serial Monitor window are the same as the serial number printed on the ID card
