RFID device and method for manufacturing the RFID device
The invention relates to an RFID device comprising: a layer of flexible laminar material, comprising: an outer face, and an inner face, and an RFID tag, fixed to the inner face of the layer. Said inner face comprises a coating, with the RFID tag being encapsulated between the inner face and the coating.
1. An RFID device comprising:
a single layer ( 1 ) of flexible laminar material, comprising:
an outer face ( 2 ), and
an inner face ( 4 ), and
an RFID tag ( 5 ), fixed to the inner face ( 4 ) of the single layer ( 1 ),
wherein the inner face ( 4 ) comprises a coating ( 6 ) of thermoplastic polymer, with the RFID tag ( 5 ) being encapsulated between the inner face ( 4 ) and the coating ( 6 );
wherein the single layer ( 1 ) of flexible laminar material is a layer of textile material.
2. The RFID device according to claim 1 , wherein the single-layer ( 1 ) of flexible laminar material is a textile material.
3. The RFID device according to claim 1 , wherein the RFID tag is fixed to the inner face ( 4 ) of the single layer ( 1 ) by an adhesive.
4. The RFID device according to claim 1 , wherein the coating ( 6 ) is a thermoplastic polymer.
5. The RFID device according to claim 4 , wherein the thermoplastic polymer is polyurethane.
6. The RFID device according to claim 1 , wherein the outer face ( 2 ) of the single layer ( 1 ) of flexible laminar material comprises a second coating ( 3 ).
7. The RFID device according to the claim 6 , wherein the coating ( 6 ) and the second coating ( 3 ) are of the same material.
8. The RFID device according to claim 1 , wherein the device comprises a second layer ( 7 ) of flexible laminar material sandwiched between the coating ( 6 ) and the inner face ( 4 ), wherein the second layer ( 7 ) of flexible laminar material is additionally sandwiched between the coating ( 6 ) and the RFID tag ( 5 ).
9. The RFID device according to claim 1 , wherein the RFID tag is made of aluminium.
10. A method for preparing an RFID device according to claim 1 , comprising the following steps:
