Note
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.

HI, Can this RFID read school ID? Does anyone know? thx
Hi there, If your school ID card is compatible with it that you can work with.
Is there any existing module: 125Khz RFID module - UART, I need this for its 150mm maximum distance. The other model on, Electronic brick - 125Khz RFID Card Reader, just 70mm maximum distance. Thank you.
Sorry,we don't have one like you said.
Hello, this module is in stock at present. Any other question?
The module work fine (or at least I guess). I have bought tags sold on the website and I have signal which change on the led pin (I have not yet try to develop and arduino application - it takes time to less time to check at hardware level).

Hey, Can I use this to write information in the cards/tags ? thanks
Hi , it can not use for writing data to cards/tags.You can refer to the module "13.56Mhz RFID module" , just it is in the different frequency card.
Is there anyway to improve the distance in which it would pick up the RFID tags I'm using? Currently the tags have to be within 10-15mm of the actual antenna to set it off. Let me know. Thank you.
The reading distance depends on many factors i.e tag size, antenna size, tag and antenna orientation, etc. In the current case you can use external booster circuit to improve reading distance.
Hi there, please refer to the link to configure the serial port on raspberry, **https://github.com/TFmini/TFmini-RaspberryPi** thanks.
Oops, I found this topic on the forum. http://www.seeedstudio.com/forum/viewtopic.php?p=852
Would it be possible to send me the antenna portion of the schematic? It appears to be just an opamp with some discretes, maybe I can modify it to suit my antennas.
Hi , I am sorry that you can not , as this is a reader.
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
Do you have a timetable on when? We are looking into buying 1500-2000 from you guys, to begin with.
Hi, I tried it anyway, and guess what, it works :D
thx
Please drop mail to techsupport@seeed.cc, i will send the code. thanks.
I am using the 125kHz 5-tag sample pack and neither this module or the mini-LF module can read any of the tags with the sample code from the wikipedia and the github repository. Please advise...
