Use The RDM880 To Read&Write The ISO14443 Type-A RFID Card/Tag

We have the 125KHz RFID reader module RDM630, it can read the 125KHz RFID card and tag, but it can not write the data into these card and tag, so when you meet the R/W requirement of your RFID project, you can choose another our RFID module : RDM880. It’s a 13.65MHz RFID reader and can read/write the ISO14443 Type-A RFID card (Mifare Care).

Here we show you a demo about how to using a Foca with RDM880 to read and write a 13.56MHz ISO14443 Type-A card and tag.

First, connect the RDM880 to Foca with 4 wires – GND,VCC,TX and RX. Put the power switch on Foca to 5V.  Then, put the card or tag on the PCB antenna of RDM880.

Download the zip here, open the DEMO.exe, and choose the COM of Foca and change the baud rate to 115200kbps as the show below:

Select the “ISO 14443 Type-A Command” tag, and select the “idle module” in “Type-A Command”- ” REQA” selection. Press the sending button, then the module will reply the success information on the right window:

the style of the card:0400

Go on to press the sending button of “Anticoll” , the module will reply like:

Multi-card flag:00
Card Serial Number :2CAEF604

Fill the Serial Number in the “Select” selection, and press the sending button again, the module will reply:

the UID of the card to be selected is:2CAEF604

Skip the sending button of “Halt”, now you can using the “Read card” and “Write card” button to read and write the 13.56M RFID card or tag now.
