A transaction product includes a support member, an electrical circuit, a button and an account identifier. The support member at least partially depicts a measurement device. The electrical circuit is coupled to the support member, and the button is in communication with the electrical circuit such that user interaction with the button activates the electrical circuit causing the electrical circuit to automatically indicate a reading of the measurement device. The account identifier links the transaction product to an account or record and is machine readable. Other cards, products, assemblies and methods of using such cards, products and assemblies are also disclosed.
