Abstract: A metalized circuit suitable for application as a radio frequency antenna is produced by forming an antenna coil pattern on a flexible substrate. The antenna coil pattern is formed using a conductive ink which is patterned on the substrate. The conductive ink is cured and an electrical-short layer is formed across the coils of the conductive ink pattern. An insulating layer is formed over top of the electrical-short layer, a metal layer electroplated on top of the conductive layer, and then the electrical-short layer is removed. The use of the electrical-short layer during the electroplating allows for the voltage at the different points on the conductive ink layer to be relatively similar, so that a uniform electroplate layer is formed on top of the conductive ink layer. This results in a better quality radio frequency antenna at a reduced cost.

Abstract: The present invention describes a system wherein an RF ID card uses a user interface, such as a keypad, to input a password. The password is encrypted and sent to an RF ID reader. Since the password is not permanently stored on the RF ID card, someone stealing the RF ID card cannot use the RF ID card to impersonate a user.
