OpenPCD is a free hardware design for Proximity Coupling Devices (PCD) based on 13,56MHz communication. This device is able to screen informations from Proximity Integrated Circuit Cards (PICC) conforming to vendor-independent standards such as ISO 14443, ISO 15693 as well as proprietary protocols such as Mifare Classic. Contactless cards like these are for example used in the new electronic passports.
OpenBeacon is a free design for an active RFID device which operates in the 2.4GHz ISM band. The device contains a unique serial number, but may have other information. OpenBeacon is designed as a transceiver device and therefore both transmits and receives radio waves. The intention of this project is to offer a wide range of use cases such as visitor or item tracking and wireless remote control with a free self-contained and low-cost RFID design.
