Data Flow in an Application
A software application that is designed to read data from a contactless data carrier (transponder) or write data to a contactless data carrier, requires a contactless reader as an interface. From the point of view of the application software, access to the data carrier should be as transparent as possible. In other words, the read and write operations should differ as little as possible from the process of accessing comparable data carriers (smart card with contacts, serial EEPROM). ...
