Abstract:
This work describes an RFID reader system based on an emulated file system to be used in SD-capable systems. Off-the-shelf SD-compliant HF-RFID readers, generally, use the SDIO interface for connecting to computers and PDAs. Therefore, the usage of SDIO-compatible SD card readers is essential to assure correct operation. In contrast to the adoption of SDIO, this work shows an approach to be used with every SD card reader, not necessarily requiring the SDIO specification. This leads to an HF-RFID system to be applied in computer environments (PDA, PC, etc.) where independence of operating systems and special drivers is of great importance. Adding RFID functionalities to existent systems could help to minimize the gap between real and digital world. This approach offers this particular functionality to any SD-compliant host device.
