Abstract

The invention relates to an electronic device (10) and a method for handling data communication with such an electronic device. The electronic device combines, on the one hand, a data carrier interface including a slot (13) for receiving a data carrier, and on the other hand a Near Field Communication (NFC) interface including an RF antenna (15) connected to a circuit (16) for acquiring data modulated in an electromagnetic wave. The antenna (15) is positioned adjacent to the data carrier slot (13), such that the NFC interface is operable to acquire data stored on an NFC tag (33, 34) positioned in the slot. A data carrier (30) for use with the electronic device may take the shape and size of a standard carrier usable with the data carrier interfaced, such as a Memory Stick, while in fact lacking a data memory accessible by the data carrier interface. Instead, the NFC interface is configured to acquire data from the much simpler and cheaper NFC tag attached to the data carrier. The acquired data may include a communication address to a remote data memory, which can be accessed transparently as if data was communicated to or from the inserted data carrier.
