This project demonstrates how to interface an RFID (Radio Frequency Identification) reader module with an Arduino Uno to read RFID tags. The UID (Unique Identifier) of the detected RFID tag is ...

Arduino UNO/Nano/Mega operates at 5V logic. However, the MFRC522 works at 3.3V logic level, and is not 5V tolerant. If using one of these microprocessors: The solution to both a.) and b.) is trivially ...

Security researcher [Fran Brown] sent us this tip about his Tastic RFID Thief ... AA batteries and a custom PCB using an Arduino Nano to interpret the reader’s output. When the reader sees ...

RFID and BLE are wireless technologies that enable communication and data exchange between devices and readers. They have different advantages and disadvantages depending on the application and ...

allowing for a real-time waveform display of low frequency RFID tags. The LF sniffer makes use of a cheap USB sound card, as well as a relatively simple reader constructed from a handful of easy ...
