RFID tag for a tamper proof attachment to an object such as a licence plate

A method for providing a tamper proof attachment of an RFID tag to an object, the method comprising:

• providing a lower housing configured to be attached to the object;
• providing an upper housing configured to be attached to the object and to be mated with the lower housing, wherein in a mated state, the lower housing and the upper housing form an inner chamber and the upper housing laterally surrounds the lower housing;
• mating the upper housing with the lower housing while positioning an antenna unit in the inner chamber between the upper housing and the lower housing and attaching at least one first portion of the antenna unit to the lower housing and at least one second portion of the antenna unit to the upper housing;
• attaching the lower housing and the upper housing, between which the antenna unit is positioned, to the object such that:
• when someone tries to remove the RFID tag from the object, the upper housing has to be removed before the lower housing can be removed;
• and
• b) when the upper housing is removed from the object, a distance between the upper housing and the lower housing changes and the antenna unit breaks because the at least one first portion of the antenna unit remains attached to the lower housing and the at least one second portion of the antenna unit remains attached to the upper housing.
