Chip card (5) capable of communicating with an external device (3) over a logical interface (4), standardized data units (20) being defined for this communication. The chip card has a ROM and an EEPROM. The functionality that is made available through the chip card when a data unit (20) is received over said logical interface (4) is determined in the EEPROM, for example through an APDU handler (512) implemented in the EEPROM.
