Data exchange with an m2m device using short range radio communication

A system, comprising:

• a device attachable to an object, the device comprising:
• a control module for receiving measuring data from at least one sensor and/or for controlling at least one actuator;
• and
• a communication module for communicating with an external reader unit via a radio connection using a radio field, wherein during the communication with the reader unit the communication module can be supplied with power using the radio field and the communication module is configured to store data received from the reader unit in a memory of the device and/or to read data to be transmitted to the reader unit from the memory, while the communication module is supplied with power using the radio field;
• and
• a reader unit configured to generate a radio field for establishing a radio connection to the device and to receive data from the device or to transmit data to the device via the radio connection.

A method for communicating with a device that is attachable to an object, the method comprising:

• establishing a radio connection between a communication module of the device and a reader unit using a radio field generated by the reader unit;
• supplying the communication module with power using the radio field during the communication;
• storing data received from the reader unit in a memory of the device, while the communication module is supplied with power by the radio field;
• and
• forwarding the stored data from the memory to the control module of the device, when the control module is supplied with power by a power supply means of the device.

A method for communicating with a device that is attachable to an object, the method comprising:

• collecting data with a control module during the operation of the device;
• storing the data in a memory of the device, while the control module is supplied with power by a power supply of the device;
• establishing a radio connection between a communication module of the device and a reader unit using a radio field generated by the reader unit;
• supplying the communication module with power using the radio field during the communication;
• and
• reading the data from the memory and transmitting the data to the reader unit, while the communication module is supplied with power by the radio field.
