RFID 13.56 Mifare Classic 1K tags with NXP MF1S50yyX/V1 chipset in stock


MOD-RFID1356MIFARE RFID reader / writter based on NFC PN532 chip was recently introduced but we had no tags for it.

Now we stock 5 different tags:

MOD-RFID1356MIFARE NFC / RFID reader writer for MIFARE 13.56Mhz tags


MOD-RFID1356MIFARE is re-design of our popular RFID card readers. It’s based on NXP PN532 chip and can read and write in ISO/IEC 14443A/MIFARE tags.

Like with MOD-RFID125 and MOD-RFID1356 it’s extremly easy to use. It connects via USB to any computer and creates HID keyboard or CDC serial port. There is no need for any drivers and switching between the modes is very easy with one push button.

WiKi description explains how to use. Read distance is up to 15 cm for ISO cards. We will stock soon 4 different types of tags: ISO card, clamshell, keychain and adhesive sticker.



MOD-RFID1356 is USB stick which can emulate HID keyboard and CDC Serial port, you can switch between the two by simple press and hold key on it.

You can use MOD-RFID1356 with any PC or board with USB host like A13 / imx233 Olinuxino, Raspberry Pi etc.

Today at 17.00 o’clock our local Bulgarian time (GMT+2) we will post on Twitter our questions.

You have one hour to reply to our tweet with the correct answer.

At 18.00 o’clock we will count the correct answers and ask random.org to generate random number in range then announce the winner and ship the board by airmail in Monday.

Good Luck!

RFID logger with Web server interface made with iMX233-OLinuXino-MAXI and MOD-RFID125


MOD-RFID125 and MOD-RFID1356 are USB RFID readers for 125Khz and 13.56Mhz RFID tags. They both support keyboard emulation mode and CDC Serial port communication mode and can be used with iMX233-OLinuXino-MAXI.

The project on GitHub creates RFID logger which logs when user approach with it tag and is controlled via web interface.

You should download the project from GitHub and build it then add rfid.php  to your web server directory.



PIC32-PINGUINO is Arduino like board which works with Pinguino IDE.

Several new demo examples are uploaded on our web https://www.olimex.com/dev/pic32-pinguino-otg.html

1. MOD-GPS demo example with our GPS module

2. MOD-CC2450 demo example with our low energy Bluetooth module (still not released on our web 🙂 )

3. SHIELD-EKG-EMG demo example how to interface this shield to Pinguino and measure pulse and muscle activity

4. MOD-MP3-X demo example how to play MP3 files with Pinguino

5. Sending and receiving calls and SMS with MOD-GSM and Pinguino

6. Connecting to Bluetooth enabled devices with MOD-BT and Pinguino

7. Interfacing MOD-ZIGBEE-PIR with Pinguino

8. MOD-RTC real time clock interfacing with Pinguino

9. Reading 13.56Mhz RFID tags with Pinguino and MOD-RFID1365-BOX

all examples have readme.txt inside which explains the functionality

Product review: RFID solutions from OLIMEX. RFID readers and tags


Olimex offers RFID readers for two frequencies: 125kHz and 13.56Mhz.

MOD-RFID125 and MOD-RFID1356 are USB dongles which could emulate USB HID Keyboard and USB CDC Serial COM port. You switch easy between the two functions by pressing and holding the button on top of them for more than 3 seconds.

In USB HID Keyboard mode MOD-RFIDxxx acts like keyboard, as soon RFID tag is approached and read correctly MOD-RFIDxxx will send the RFID code as HEX string ending with Carriage Return. This allow your PC software to read RFID tags without using special functions just as reading input from your normal PC keyboard.

Note that MOD-RFIDxxx do not distruct your normal PC Keyboard work, so you can use both Keyboard and MOD-RFIDxxx at same time without conflicts.

If you want to read the tags in your software by Serial COM port no problem – press and hold the MOD-RFIDxxx button and it will detach the USB HID Keyboard and attach to USB CDC Serial COM port emulator, so you can read the tag info by reading the serial COM port.

Here below is picture of what happens in Notepad when MOD-RFIDxxx is attached to USB port and in HID keyboard mode, when tag is approached:


how many times to read and send TAG info is possible to setup in Serial port mode with special commands which are described in MOD-RFIDxxx users manual.

Here below is picture of what happens in Hyperterminal when MOD-RFIDxxx is attached to USB port and in CDC serial COM mode, when tag is approached:


MOD-RFID125-BOX and MOD-RFID1356-BOX have same functionality as MOD-RFID125 and MOD-RFID1356 but also are equiped with UEXT conector which allow them to be connected to any of our boards with UEXT like DuinoMite for instance.

In this mode you should power MOD-RFIDxxx with the external power supply and connect your board with UEXT cable then you can use the commands which are described in the MOD-RFIDxxx-BOX users manual to communicate.

Olimex have several different RFID-TAGs for 125 kHz and 13.56Mhz in these shapes:
