An apparatus, a method and a computer program, the apparatus including: an interface configured to detect a first electrical signal, the first electrical signal being provided by a transceiver; secure transaction circuitry having a first power state and a second power state, the secure transaction circuitry being configured, when in the second power state, to perform a transaction, using the transceiver, with a further apparatus; memory circuitry having power states; and control circuitry configured, in response to detecting the first electrical signal, to control the secure transaction circuitry to switch from being in the first power state to being in the second power state, without changing a power state of the memory circuitry. |
