1. A biometric system comprising:
a contactless smartcard including a biometric arrangement and a wireless power transfer arrangement; and
an enrollment assistance device for power supply to the contactless smartcard allowing enrollment operation of the biometric arrangement, the enrollment assistance device comprising:
a carrier having a first surface portion for arrangement of a user device including a wireless power transfer arrangement, and a second surface portion, spaced apart from the first surface portion, for arrangement of the contactless smartcard;
a first wireless power transfer arrangement supported by the carrier and arranged to form a first wireless power transfer link with the wireless power transfer arrangement of the user device when the user device is arranged on the first surface portion of the carrier;
a second wireless power transfer arrangement supported by the carrier and arranged to form a second wireless power transfer link with the wireless power transfer arrangement of the contactless smartcard when the contactless smartcard is arranged on the second surface portion of the carrier; and
a conductor arrangement supported by the carrier and conductively connecting the first wireless power transfer arrangement and the second wireless power transfer arrangement, in such a way that power transfer is enabled from the user device to the contactless smartcard, via the first wireless power transfer link, the conductor arrangement, and the second wireless power transfer link,
wherein the contactless smartcard is fixed by an adhesive on the second surface portion of the carrier of the enrollment assistance device.
