OCR640 – Operational Description
OCR640 is an USB connected passport reader which has a Camera Imager and a RFID contactless reader.
The camera is used to capture images by the host application, which then decodes the passport MRZ
data. The MRZ data is then sent to the RFID reader to authenticate with the RFID chip in the passport to
read the data. The following figure shows the hardware architecture of OCR640.
