The bottom of the second depression is arranged in the smart card body less deeply than the highest region of the coupling turns which faces the second depression.

Methods for manufacturing RFID devices are provided with self-limiting heating features. Inducing current flow through the antenna of an RFID device (e.g., by exposing the antenna to a changing magnetic field) will increase heat of the RFID device, thereby curing/sintering elements of the RFID device (which may include curing an adhesive used to couple the antenna to an RFID chip) without applying external heat, which typically heats regions of the RFID device that were not intended to be heated (e.g., the substrate to which the antenna is secured). Inducing current flow through the antenna of an RFID device will reduce the resistance of the antenna, which has a heat-limiting effect that prevents overheating of the RFID device. Inducing current flow may also change the resonant frequency of the antenna, which may provide another heat-limiting effect.

A carrier for securing a tracking component includes a housing. The housing includes a recess formed into a face of the housing that is adapted to secure the tracking component. The recess includes a wall that surrounds a periphery of the recess and a hole formed through a bottom surface of the recess.
