Abstract

The invention relates to a device wherein a handheld battery-powered unit communicates with an external handheld peripheral unit by direct electrical contact, wherein said battery-powered unit at least comprises a processor and a storage medium or media, and also has a communication port for peripheral units, characterised in that said handheld peripheral unit comprises at least one or more battery cells and a data chip, wherein the data chip of the said peripheral unit at least comprises a storage medium in which there is stored software that can be exchanged with the battery-powered handheld unit.

Claims

1. A device wherein a handheld battery-powered unit communicates with an external handheld peripheral unit by direct electrical contact, wherein said battery-powered unit at least comprises a processor and a storage medium or media, and also has a communication port for peripheral units, wherein said handheld periperhal unit comprises at least one or more battery cells and a data chip, wherein the data chip of the said peripheral unit at least comprises a storage medium in which there is stored software that can be exchanged with the battery-powered handheld unit.

2. A device according to claim 1, wherein said peripheral unit comprises a system connector that is suitable for being snapped on to the handheld battery-powered unit.

3. A device according to claim 1, wherein said software is communicated between the handheld battery-powered unit and the peripheral unit using AT commands.

4. A device according to claim 3, wherein said software comprises applications to enhance the functionality of the handheld battery-powered unit.
