Abstract: A biometric module implemented on a single integrated circuit chip is configured to perform processing as part of a function associated with a device that performs contactless communication with a terminal. The module comprises a power-harvesting unit to induce a voltage from a wireless signal received at an antenna of the device; one or more components configured to process functions in the digital domain; one or more components configured to process functions in the analogue domain; and first and second voltage regulators each having inputs for receiving an input voltage induced by the power-harvesting unit. The first voltage regulator outputs a first voltage to the components processing functions in the analogue domain and the second voltage regulator outputs a second voltage lower than the first voltage to the components processing functions in the digital domain.
