A payment device includes a memory, a processor coupled to the memory, a communications module coupled to the processor and configured to interact with a payment terminal, a sound-producing element coupled to the processor, and an associated body portion. The memory is configured to store at least one representation of at least one sound and the processor is configured to cause the sound-producing element to produce a sound corresponding to the at least one representation of the at least one sound when such representation is stored in the memory, responsive to the communications module interacting with the payment terminal, substantially without usage of a battery on the device. Visual stimuli can be employed in addition to or in lieu of sounds. Sounds can be downloaded to devices with or without batteries, as part of a service offering. |
