The next thing is to select what type of protocol we will use to communicate to the RFID.

The RFID is the USB ACR122u.Īfter we install the pyscard, we can test the RFID communication directly from the Python console: The Smartcard library that I am implementing with Python is pyscard to control the communication with the reader.

These code examples were tested in a Mac OS 10.13.1 and Python 2.7. This is important because with the right command, we may change the light, mode or buzzer configuration.Īs usual, I will start with a list of components to understand the process of emulation.

One thing to have in mind is that we are talking directly to the hardware, so we can access special places to extract data, even we can change behaviors in the ACR122u hardware components.

How to test these methodologies or how to create a new NFC penetration testing tool are essential. Moreover, the main reason to learn how to emulate a contactless card is to be prepared and aware about the dangerous scenarios and limitations of the NFC payment technology. The first could be that it is difficult to implement a native language to talk to the card reader, and it changes depending of the native chip. The idea of emulating is not very well documented for many different reasons.

Some users could implement a RFID device as contactless card to make transactions, validate an individual entrance or to access certain building or hotel. To mimic a contactless card behavior, an emulation is required. We can see this in almost every smart-phone or gadgets to make payments. You can learn more about that from my first post about NFC.Įmulate a card is essential in the actual NFC technology. Those commands could be Pseudo APDUs or Native orders. In order to implement a RFID reader as card emulator, we should be able to program the hardware using specific configuration commands to initialize it in that specific mode. I will focus on card emulation after a difficult poll: In the same way, NFC protocol is divided in three categories: RFID is divided is different categories: low frequency (LF), high frequency (HF), ultra-high frequency (UHF)… Because we have different technologies using high frequency, I will talk specifically about ISO/IEC 18000-3 which standards for Near Field Communication (NFC). In this post specifically, I will use the PN532 NFC Controller chip from my USB RFID ACR122u. Card emulation is a technique that many different RFID chips support.
