RFID Starter Kit - Retail

Replacement:RTL-11839. We've updated the ID-12 RFID Module to the new ID-12LA which has a lower voltage input. This page is for reference only.

This kit includes everything you need to get started with RFID. It includes a USB RFID board, ID-12 RFID reader, and 2 RFID cards.

The RFID USB Reader is a simple to use, USB to serial base unit for the ID-2, ID-12, and ID-20 readers. Simply plug a reader into the headers and attach a miniUSB cable. Open a terminal program of your choice at 9600bps 8N1, then scan your 125kHz ID tag and the unique 32-bit ID will be shown on the screen. The unit is based on a FTDI chip and comes with a read LED and buzzer.

The ID-12 is a very simple RFID reader module. It plugs directly into the USB reader to allow you to read RFID tags through a USB connection. Power the module, hold up a card, and get a serial string output containing the unique ID of the card.

Note: This version comes with blank, unbranded RFID cards.

    The new-product post says this kit has 5 RFID cards, but this page says only 2. I'm assuming you haven't updated this page. Please do so (but don't update the price; unless you'll bump it down so broke-ass nerds like me can afford one)...

    thank you

    I just purchased two of these kits to play with but want to get a head start. I have an application where I want to leave a Card next to the sensor and actually poll the reader say every 2 seconds to detect if the Card is still within range. (Kinda like a proximity detection except with unique ID) Can I force this to do this? Maybe by cycling the power or something? Any ideas or thoughts would be appreciated! Thanks!

      Hmm. The way it normally works is that when a card enters the field, you get a single serial-number response, and nothing else unless the card exits the field and returns. I think you're on the right track in power-cycling the reader or using the reset line, but unfortunately the reset line is tied high on the board. With some fine surgery you may be able to hack it out and connect it to e.g. the DTR output of the FTDI chip to allow you to control it from the host computer; sorry in advance if this isn't practical. You could of course play with this using the barebones parts in the kit as well. Good luck and let us know what you find!
