Does anyone know a 125khz RFID Module with 3.3v?

Does anyone know a 125khz RFID Module with 3.3v?
Or what would be the easiest way of connecting a 5V RFID Module to Beaglebone?
Thanks in advance!

add a level shifter, something like a https://www.sparkfun.com/products/8745

Easiest way is to simply use a USB dongle.

thank you both for your answers.
so I could either use a level shifter, preferably with a breadboard
or
if I would go the USB way, I would need an USB Hub (because I’ll have more devices) or go straight to beagleboard-xm?

well, if you are not afraid of soldering/breadboard, go for the level shifter
