A tag has circuitry with a communication portion that can transmit and receive wireless signals, including wireless transmission of data blocks that each have a predefined configuration with a plurality of data slots. The circuitry includes a further portion that, in response to receipt through the communication portion of a wireless communication containing a request identifying a set of plural data items, populates respective data slots in one data block with respective data items from the set, and then causes the communication portion to effect wireless transmission of that data block.
