      Description

      One of the coolest part of IoT project must be the identification technology, 125Khz RFID module – UART is the most popular RFID module that produced by Seeed, By connecting this RFID module to Arduino or Raspberry Pi, you are able to build projects that can be used in office/home security, personal identification, access control, anti-forgery, interactive toy and production control systems etc.


      Features

      • Support external antenna

      • Maximum effective distance up to 50mm

      • Less than 100ms decoding time

      • UART TTL interface

      • Support EM4100 compatible read only or read/write tags

      • Built-in external bi-color LED and buzzer driver

      • Small outline design


      Note:

      Module will notify whenever 125khz tag approaches, tag serial number will be send via TX pin. Easy way for a RFID module on MCU projects or PC connnection via UartSB.

      Can this reader ready multiple RF tags at one time? The EAS tags for anti-theft purpose.

      HI,You'd better not do it , as the different labels will cause interference.

      BTW,card can’t be read again within the range of read antenna after read once. User must move it out of reading antenna range first, swipe card again & can be read.

      Will this read the tags that are implanted in pets (US based)?

      Hey alanv73 I can confirm that this works with implantable chips, I have one in my hand and one in my dog, both work with this reader. however I know there are some proprietary chips out there such as the avid brand which i havent tested, so your mileage may vary

      Hello folks. I bought EM4100 tags from Amazon and this 125khz reader works great with them. But, the tags are printed on the outside with a unique code that is not the same as the ID that the reader sees. How to correlate the tag's printed code with the ID seen by the reader? Example: tag printed on plastic "0009429268" and reader sees "000042E1E5" in UART/TTL mode. Thanks!

      Answering my own question here... because I matched up the wrong TAG with the reader output. The value printed on my plastic tag is the decimal representation of the first 10 bytes of the reader output. So if the reader gives me 000042E1E5, then the tag should be printed with 0004383205. Easy enough when you organize your data correctly.

      Can it write? Can it read anything beside the ID?
