Smart Card Readers & Writers
The reader provides a path for an application to send and receive commands from the card. Each manufacturer provides a different protocol for communication with the reader.
- First, users have to communicate with the reader.
- Second, the reader communicates with the card, acting as the intermediary before sending the data to the card.
- Third, communication with a smart card is based on the APDU format. The card will process the data and return it to the reader, which will then return the data to its originating source
