Abstract
The present invention is directed towards authentication tokens that are completely embedded in a non-conductive enclosure. The invention is based on the insight that it would be advantageous to separate the electronic data personalization of such tokens from the visual device personalization. The present application concerns an authentication token that allows communication with an external unit after the production of the nonconductive enclosure, in order to transmit or receive device identification data. As this communication need only take place during the manufacturing process, a low-power close-range transmission technique such as inductive coupling, capacitive coupling, or RFID communication suffices for this purpose. Accordingly, the present application discloses a method for manufacturing authentication tokens, and a token manufactured according to said method.
