Motor Encoder |
|
 The new motorized Proximity Card Feeder was developed for secure transactions on proximity chip cards such as Mifare®.
Due to a clear defined stop position of the card below the antenna, all transactions are performed without any errors.
The feeder is controlled by a microprocessor, which takes advantage of three micro switches to detect the card position and movement. Once a card is inserted into the front, the microcontroller moves the card to the antenna position.
To interface the chip, a standard serial port (RS.232) is available. If a non proximity card is used, the controller will eject the card at the front after a timeout. If reading or writing is finished, the card can be moved either to the front or it can be swallowed (output at the back). If a card is inside the reader and the user tries to insert a second card, the microcontroller rejects both cards at the front. The movement of the card is controlled via an I2C Bus or with digital signals.
All movement controls as well as the status signals of the switches a supplied via the 8 Bit digital I/O port.
Upon request, the serial interface to the reader can be used to control the card movement.
The frame is made of stainless steel to ensure a durable operation even in harsh environments. All rubber parts a made of a long life and durable material.
The motor encoder is operated by a single voltage.
