Hello, I have been trying to make this reader to work with my Arduino (Uno or Mega) with my company security card from HID (format H10301 at 125Khz) but I cannot read anything, anyone from here had successfull reading with HID card?

Thanks, but my point is that I want a cheap reader that would read my company card. Does anyone have a schematic of their connection with a Arduino?

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

I tried this module with an avian leg tag like this http://www.buyrfid.co.uk/store/index.php?route=product/product&product_id=87&search=cyan It works perfectly. Now all I would like to do is use a different antenna as I have a significant investment in already made antennas. These are my antennas http://www.priority1design.com.au/shopfront/index.php?main_page=product_info&cPath=1&products_id=7 Is there a way to 'tune' this board to work with my antennas?

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.

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 we use it to emulate a tag?

125Khz RFID reader  is not compatible with Emulate tag. It supports only 125khz EM4100 compatible tags.

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

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.
