Description: The SparkFun RFID USB Reader is a simple to use, USB to serial base unit for the ID-3LA, ID-12LA, and ID-20LA 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.
This new revision uses SMD headers for the RFID module, and has a solder jumper which allows you to disable or enable the buzzer.
Note: This product does not come with the RFID reader. Check below for compatible readers.

RFID tech can be tricky but using this with the Sparkfun Antenna has been a perfect combo. Good, clean reads with all our RFID chips has made life much easier for us!
Currently this device has a connection to the card present pin 5 of the ID-12LA unit, but this is not very useful. The ID unit is set to ASCII output, not Magnetic card emulation, therefore this breakout board should have the “tag present” pin (pin 6) wired to the board not pin 5 (which is only active in Mag. Card Emulation). In the datasheet, pin 6 is labelled as “Future”, but the future has arrived…this pin goes high when a tag is present, and goes low when the tag is removed. This board should be upgraded for this functionality.
Using the ID Innovations125kHz readers, the tested real world maximum ranges of the modules with the RFID tagged items are listed below:
Card = 0" (you need an external antenna) Button = 0" (you need an external antenna) Glass Capsule = 0" (you need an external antenna)
Card = 2" - 2.25" Button = 1" - 1.5" Glass Capsule = 0.75" - 1"
Card = 2.75" Button = 2" Glass Capsule = 0.75"
The range results were taken from the demo video between 6:13-9:10 => https://youtu.be/FLjV5BT9slg?t=6m13s .
Multiple RFID USB Readers
If you place 4 of these RFID readers with the ID Readers, there will be RF interference from each other. Customer had issues with this setup. When he placed them at a distance of about 15-20cm+ between each other, they were able to get them working.
