wherein the control unit (2) is configured to selectively, when the proximity sensor (8) detects presence of the object within the detection zone (20), activate the Bluetooth transmitter (6) to transmit a data package comprising an identifier (MID) of the electronic tag.

2. The electronic tag of claim 1 or 2, wherein the Bluetooth transmitter (6) is a BLE transmitter.

3. The electronic tag of any one of the preceding claims, wherein the control unit (2) is configured to activate the Bluetooth transmitter (6) in a broadcast mode to transmit the data package.

4. The electronic tag of any one of the preceding claims, wherein the control unit (2) is configured to activate the Bluetooth transmitter (6) to repeatedly transmit the data package during a preconfigured time period.

5. The electronic tag of any one of the preceding claims, further comprising a storage memory (4) which is configured to store the identifier (MID), wherein the control unit (2) is configured, before activating the Bluetooth transmitter, to retrieve the identifier (MID) from the storage memory (4) and provide the identifier (MID) to the Bluetooth transmitter (6).

6. A data collection system, comprising:

a plurality of system devices (100),

an electronic tag (1) as set forth in any one of claims 1-5 and arranged to be associated with a respective system device (100) among said plurality of system devices (100), wherein the identifier (MID) of the electronic tag (1) is a device identifier which is unique to the associated system device (100), and

a computer system (50) configured to receive the device identifier (MID) from a portable electronic device (30) that has intercepted the data package transmitted by the electronic tag (1) and extracted the device identifier (MID) from the data package.

7. The data collection system of claim 6, wherein the electronic tag (1) is configured and arranged such that the associated system device (100) is located within the range of the Bluetooth transmitter (6) in the electronic tag (1) and all other system devices among the plurality of system devices (100) are located beyond the range of the Bluetooth transmitter (6).

8. The data collection system of claim 6 or 7, wherein the plurality of system devices comprises exercise devices (100).

9. The data collection system of claim 8, wherein each exercise device (100) comprises a monitoring system (111) for determining workout data for the exercise device (100), and a wireless transmitter (113) for transmitting the workout data together with the device identifier (MID) that is associated with the exercise device (100), for receipt by the computer system (50).

10. The data collection system of claim 9, wherein the workout data comprises at least one of a weight being used with the exercise device (100) and a number of repetitions of using of the weight.

11. The data collection system of claim 9 or 10, wherein at least a subset of the exercise devices (100) are arranged in a common facility, the data collection system further comprising a relay device (60) which is arranged in the common facility and is configured to receive the workout data and the device identifier (MID) from the wireless transmitter (113) and transmit the workout data and the device identifier (MID) to the computer system (50).

12. The data collection system of any one of claims 9-11, wherein the computer system (50) is configured to, after receiving the device identifier (MID) from the portable electronic device (30) and after receiving the workout data and the device identifier (MID) transmitted by the wireless transmitter (113) of the exercise device (100), transmit information related to the workout data to the portable electronic device (30) or to a feedback device associated with the exercise device (100).

13. A method of operating a portable electronic device (30), comprising:

receiving a data package from an electronic tag (1) according to any one of claims

1-5,

extracting the identifier (MID) of the electronic tag (1) from the data package, and communicating the identifier (MID) to a computer system (50).

14. The method of claim 13, further comprising: obtaining inertial data from an inertial sensor (36) in the portable electronic device (30), and detecting, based on the inertial data, a predefined docking state on the electronic portable device (30) in relation to the electronic tag (1), wherein said communicating the identifier (MID) is enabled only upon detection of the predefined docking state.

15. The method of claim 14, wherein the predefined docking state corresponds to the portable electronic device (30) being brought into contact with the electronic tag (1).

16. The method of claim 14 or 15, further comprising determining a motion of the portable electronic device (30) based on the inertial data, wherein said detecting the predefined docking state comprises detecting that the motion represents an impact of the portable electronic device (30) onto the electronic tag (1).
