Wearable assembly

An electronics module for a wearable article, the electronics module comprising:

• a processor and at least two contacts communicatively coupled to the processor, the two contacts are arranged to be brought into contact with an identification element when positioned on the wearable article,
• wherein when the electronics module is positioned on the wearable article, the two contacts are electrically connected to one another via the identification element, and wherein the processor is operable to measure impedance of the electrical connection formed between the two contacts by the identification element so as to read identification information that is encoded into the impedance of the identification element.

A method of identifying a wearable article, the method comprises:

• positioning an electronics module on a wearable article such that two contacts of the electronics module are brought into contact with an identification element of the wearable article and electrically connected to one another via the identification element;
• and
• measuring impedance of the electrical connection formed between the two contacts by the identification element so as to read identification information that is encoded into the impedance of the identification element.
