0039A02C-253/IDE-SD-MIF-AGFA
REVISION 1.0, 2008-04-02
The IDE_SD_MIF_AGFA is a RFID Read-/Write-Device (short: reader) which is compatible to all
Mifare cards. The reader also supports ISO14443A/B and ISO15693 and all cards compliant to
these standards. It provides a serial interface RS232 to output or exchange data with a host
computer and a 13,56MHz inductive interface to supply power to and exchange data with the
Mifare/ISO compliant card (or other available form-factors such as tags, key-fobs).
Mounting and Connection
The reader generates a magnetic field with the frequency of 13.56MHz which is influenced by any
electrically conductive material in close proximity to the device. When mounting the unit, a
distance to any such material of minimum 10 cm is required to ensure that there will be no
significant degradation of the performance in terms of read range and reliability. Mounting the unit
directly to metal would result in a severe reduction of read range down to zero functionality. Care
should be taken when testing the device after mounting at a problematic environment: Read ranges
and performance vary from card to card and very much from card to tag or key-fob.
When mounting multiple readers, the distance between readers should be minimum 0.5 m in order
to avoid degradation of performance due to interference.
To connect the device to a Host computer, please make sure the host system provides an 6-pin plug
connector intended for connection of the reader
Operation
Whenever the device is connected to a proper power supply, it will switch on the internal antenna
and periodically scan for a card. Once a card has been detected, the card number is read, the data
converted and sent to the host system through the serial interface. To enable the device to read
cards, tags and key-fobs successfully, they should be placed centred above the reader.

Serial Interface
The TXD/RXD signals are compatible with RS-232 level signals. The interface operates at
2400 baud, no parity, 8 data bits, 1 stop bit. Upon detection of a valid card swipe, the
reader outputs the card number in ASCII format.
