Enrolment assistance device

A method of an enrolment assistance device of facilitating biometric enrolment of a user of a contactless smartcard comprising a biometric sensor and a wireless power transfer arrangement, the enrolment assistance device comprising:

• a carrier comprising:
• a first surface portion configured to receive a user device equipped with a wireless power transfer arrangement;
• and
• a second surface portion paced apart from the first surface portion and configured to receive the contactless smartcard;
• the first surface portion being arranged with a conductor configured to wirelessly harvest energy from the wireless power transfer arrangement of the user device;
• the second surface portion being arranged with a conductor arranged to be connected to the conductor of the first surface portion via a connector and configured to wirelessly transfer the harvested energy to the wireless power transfer arrangement of the contactless smartcard;
• wherein
• the contactless smartcard is configured to transmit a signal to the user device upon the user device being moved into position by a user in the first surface portion enabling the contactless smartcard to harvest an amount of energy exceeding an energy threshold via the conductor of the second surface portion, the signal causing the user device to provide an alert to the user that a desired position of the user device has been reached, and
• the energy threshold corresponds to an amount of harvested energy sufficient to adequately power the contactless smartcard during biometric enrolment of the user.
