    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.

    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.
