If you don't own such a module, it's not a big problem to connect the reader with GPIO pins of your RaspberryPi.

How?

Change /boot/cmdline.txt, from:

dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1

to

dwc_otg.lpm_enable=0 console=tty1

Change /etc/inittab, from:

#Spawn a getty on Raspberry Pi serial line
T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

to

#Spawn a getty on Raspberry Pi serial line
#T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

Reboot your Pi.

Connect the Reader with following PINs:

GND -> PIN 6
TxD -> PIN 10 (= GPIO 15)
RxD -> PIN 8 (= GPIO 14)
VCC -> PIN 1 (3,3V) or PIN2 (5,5V)

(GPIO PIN overview)

Use serial port with the name /dev/ttyAMA0 for RxTx and configure RxTx e.g. -Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0.
