Abstract
A secure RFID device is provided. The RFID device includes a switch module mounted in a recess of a device body. The switch module includes a switching portion configured to electrically connect terminal ends of an RFID antenna embedded in the switch body. In particular, forming the recess and mounting the switch module including the switching portion to the RFID device after final lamination of the same allows for the use of manufacturing techniques that result in RFID cards having high durability and required ISO qualities.
Claims21
A RFID device comprising:
- a device body having a first surface;
- an open-circuit RFID antenna embedded in the device body and having a first terminal end and a second terminal end;
- a recess formed in the first surface and comprising a stepped configuration with a peripheral portion at a first depth from the first surface surrounding a central recessed portion at a second depth from the first surface that is deeper than the first depth;
- a first electrical contact and a second electrical contact provided on the peripheral portion, the first electrical contact being electrically connected to the first terminal end, and the second electrical contact being electrically connected to the second terminal end;
- and
- a switch module mounted at least in part in the recess, the switch module comprising:
- a switch housing comprising a stepped configuration substantially corresponding to the stepped configuration of the recess and having a peripheral connecting portion and a central protrusion;
- a first switch contact exposed from the switch housing on the peripheral connecting portion and electrically connected to the first electrical contact;
- a second switch contact exposed from the switch housing on the peripheral connecting portion and electrically connected to the second electrical contact;
- and
- a switching portion configured to electrically connect the first switch contact and the second switch contact upon actuation by a user.

A method of manufacturing a RFID device, comprising:
- providing a planar pre-laminate, with an open-circuit RFID antenna having a first terminal end and a second terminal end, and a first electrical contact and a second electrical contact being formed on the pre-laminate, the first electrical contact and the second electrical contact being electrically connected to the first terminal end and the second terminal end, respectively;
- laminating the pre-laminate with at least one further laminate layer provided on top of the pre-laminate to form a device body of the RFID device;
- processing a region of a first surface of the device body to form a recess comprising a stepped configuration with a peripheral portion at a first depth from the first surface surrounding a central recessed portion at a second depth from the first surface that is deeper than the first depth, the recess exposing, on the peripheral portion, at least a portion of the first electrical contact and the second electrical contact;
- inserting a switch module in the recess, the switch module comprising:
- a switch housing comprising a stepped configuration substantially corresponding to the stepped configuration of the recess and having a peripheral connecting portion and a central protrusion;
- a first switch contact exposed from the switch housing on the peripheral connecting portion;
- a second switch contact exposed from the switch housing on the peripheral connecting portion;
- and
- a switching portion configured to electrically connect the first switch contact and the second switch contact upon actuation by a user;
- and
- electrically connecting the first switch contact to the first electrical contact and the second switch contact to the second electrical contact.
