Microchip - Contact

Microchip - Contact Integrated circuit (microchip) for the storage and processing of data, embedded for example in ID cards. The secure electronic medium contains e.g. the personal data: name, date of birth, place of birth, issuing office and a digitized version of the image of the holder. An ID card with contact chip must be inserted into a reader to make contact with electrical connectors to be able to read the information from it. The visible parts of the chip module are the typical gold contacts. Source : Click Here
