Badge with RFID device
An identification or security badge has a radio frequency identification (RFID) device that is on a flexible substrate of the badge. A first part of the flexible substrate, including a first part of an antenna of the RFID device, overlaps a second part of the substrate that contains a second part of the antenna, with the parts physically separated from one another. A holder of the badge may be mechanically coupled to the flexible substrate to provide the separation between the substrate parts. The holder may hold ends of the flexible substrate with clips, so that at least one part of the substrate has a curved or bowed (arcuate) shape that separates it from another part of the substrate. The separation of different antenna parts from each other means that at least part of the antenna is spaced away from a wearer of the badge.
1. A badge comprising:
a radio frequency identification (RFID) device on a flexible substrate; and
a holder having a frame with opposite ends defining a length that maintains the flexible substrate in a deformed condition providing increased thickness to the RFID device, the flexible substrate having a length longer than the length of the frame;
wherein the deformed condition includes a first part of the flexible substrate overlapping a second part of the flexible substrate;
wherein the RFID device includes one or more antennas and an RFID chip directly coupled and attached to the one or more antennas, so as to allow the RFID to interact with external readers/detectors;
wherein a first at least part of the one or more antennas is on a first part of the flexible substrate; and
wherein a second at least part of the one or more antennas is on a second part of the flexible substrate.
2. The badge of claim 1 , further including an adhesive strip along one end of the flexible substrate.
3. The badge of claim 1 , wherein the flexible substrate has a bowed shape.
4. The badge of claim 1 , wherein the holder includes:
clips on opposite sides of the frame; and
wherein the clips hold the flexible substrate to the frame, with the flexible substrate in the deformed condition.
5. The badge of claim 1 , wherein the flexible substrate includes:
a first part of the flexible substrate that includes a front surface of the badge; and
a second part of the flexible substrate that includes a back surface of the badge.
6. The badge of claim 5 , wherein the deformed condition includes the first part and the second part bulging in opposite directions from a plane of the holder.
7. The badge of claim 5 , wherein the parts of the flexible substrate have respective parts of the RFID device upon them.
8. The badge of claim 7 , wherein the respective parts include the respective first and second at least part of the one or more antennas.
9. The badge of claim 8 , wherein both of the pair of antennas are directly coupled to an RFID chip of the RFID device.
10. The badge of claim 1 , wherein the deformed condition includes separation by air space.
11. An identification device comprising:
a monolithic substrate having a first substrate part and a second substrate part;
a radio frequency identification (RFID) device on the monolithic substrate;
wherein respective portions of the RFID device are on the substrate parts;
wherein the first substrate part overlaps the second substrate part, with separation maintained between at least portions of the substrate parts in which a holder maintains the substrate in a bowed out condition providing increased thickness to the RFID device;
wherein the respective portions of the RFID device include at least portions of one or more antennas of the RFID device; and
wherein the one or more antennas are directly coupled to an RFID chip of the RFID device.
12. The device of claim 11 , wherein the identification device is a badge.
13. A method of making an identification device, the method comprising:
providing a frame having ends;
printing one or more visual material elements on a flexible substrate;
overlapping parts of the flexible substrate;
placing the flexible substrate in the frame such that the parts of the flexible substrate bulge away from a plane of the frame; and
spacing apart overlapped parts of the flexible substrate that include respective portions of a radio frequency identification (RFID) device that is on the flexible substrate wherein the RFID device includes one or more antennas and an RFID chip directly coupled to the one or more antennas, so as to allow the RFID to interact with external readers/detectors; wherein a first at least part of the one or more antennas is on a first major surface of the flexible substrate; and wherein a second at least part of the one or more antennas is on a second major surface of the flexible substrate.
14. The method of claim 13 , wherein the visual material elements include pictures, logos, or holograms.
15. The method of claim 13 , further comprising, after the spacing apart, securing the flexible substrate in a holder to maintain the overlapped and spaced apart condition.
