CF card slot RFID readers

The Compact Flash (CF) slot is a format used in portable electronic devices designed for flash memory in a standardized enclosure.
CompactFlash remains popular, and has even experienced something of a comeback, caused by improvements in the ATA interface. CF cards can be used directly in a PC Card slot with a plug adapter, used as an ATA (IDE) or PCMCIA storage device with a passive adapter or with a reader.

Typical CF card

iDtronic has designed a range of RFID readers based on this interface technology.
