Authenticity label for items
Disclosed are various embodiments of multi-layer identifier labels. In one embodiment, a multi-layer identifier label includes an upper layer bearing a public identifier, a lower layer bearing a private identifier, and an adhesive backing below the lower layer. The upper layer may be removably attached to the lower layer, and the lower layer may be non-visible underneath the upper layer. Peeling away the upper layer to reveal the lower layer may be a tamper-evident action.
1. A multi-layer identifier label, comprising:
an opaque upper layer bearing a public identifier;
a lower layer bearing a private identifier, the upper layer being removably attached to the lower layer, the lower layer being non-visible underneath the opaque upper layer;
an adhesive backing below the lower layer that attaches the multi-layer identifier label to a product;
wherein the public identifier comprises a first two-dimensional barcode, the private identifier comprises a second two-dimensional barcode, and the first two-dimensional barcode is smaller in size than the second two-dimensional barcode;
wherein the opaque upper layer bears a visual indication of a location where peeling of the opaque upper layer from the lower layer should be started by a user;
wherein a glue release element is disposed at the location between the opaque upper layer and the lower layer; and
wherein peeling away the opaque upper layer to reveal the lower layer is a tamper-evident action.
2. The multi-layer identifier label of claim 1 , wherein at least one of the opaque upper layer or the lower layer includes a hologram.
3. The multi-layer identifier label of claim 1 , wherein the opaque upper layer includes a protrusion that extends beyond an edge of the lower layer.
4. The multi-layer identifier label of claim 1 , wherein the lower layer includes a nook that recedes from an edge of the opaque upper layer.
5. The multi-layer identifier label of claim 1 , wherein an underside of the opaque upper layer bears an instruction for an end user to scan the private identifier.
6. The multi-layer identifier label of claim 1 , wherein the opaque upper layer is configured to release cleanly from the lower layer such that an underside of the opaque upper layer is non-sticky when peeled away from the lower layer.
7. A multi-layer identifier label, comprising:
an upper layer bearing a public identifier;
a lower layer bearing a private identifier, the upper layer being removably attached to the lower layer, the lower layer being non-visible underneath the upper layer;
an adhesive backing below the lower layer;
wherein the upper layer is configured to release cleanly from the lower layer such that an underside of the upper layer is non-sticky when peeled away from the lower layer; and
wherein peeling away the upper layer to reveal the lower layer is a tamper-evident action.
8. The multi-layer identifier label of claim 7 , wherein the public identifier comprises a first two-dimensional barcode, the private identifier comprises a second two-dimensional barcode, and the first two-dimensional barcode is smaller in size than the second two-dimensional barcode.
9. The multi-layer identifier label of claim 8 , wherein the second two-dimensional barcode is not a quick response (QR) code.
10. The multi-layer identifier label of claim 7 , wherein the lower layer is constructed of a tamper-evident material configured to indicate whether the multi-layer identifier label has been affixed to a surface and then removed from the surface.
11. The multi-layer identifier label of claim 7 , wherein an underside of the upper layer bears an instruction for an end user to scan the private identifier.
12. The multi-layer identifier label of claim 7 , wherein the lower layer includes a nook that recedes from an edge of the upper layer.
13. The multi-layer identifier label of claim 7 , wherein the upper layer bears a visual indication of a location where peeling of the upper layer from the lower layer should be started by a user.
14. The multi-layer identifier label of claim 13 , wherein a glue release element is disposed at the location between the upper layer and the lower layer.
15. A multi-layer identifier label, comprising:
an opaque upper layer bearing a public identifier;
a lower layer bearing a private identifier, the upper layer being removably attached to the lower layer, the lower layer being non-visible underneath the opaque upper layer;
an adhesive backing below the lower layer that attaches the multi-layer identifier label to a product;
wherein the public identifier comprises a first two-dimensional barcode, the private identifier comprises a second two-dimensional barcode, and the first two-dimensional barcode is smaller in size than the second two-dimensional barcode;
wherein the lower layer includes a nook that recedes from an edge of the opaque upper layer; and
wherein peeling away the opaque upper layer to reveal the lower layer is a tamper-evident action.
16. The multi-layer identifier label of claim 15 , wherein at least one of the opaque upper layer or the lower layer includes a hologram.
17. The multi-layer identifier label of claim 15 , wherein the opaque upper layer includes a protrusion that extends beyond an edge of the lower layer.
18. The multi-layer identifier label of claim 15 , wherein an underside of the opaque upper layer bears an instruction for an end user to scan the private identifier.
19. The multi-layer identifier label of claim 15 , wherein the opaque upper layer bears a visual indication of a location where peeling of the opaque upper layer from the lower layer should be started by a user.
20. The multi-layer identifier label of claim 19 , wherein a glue release element is disposed at the location between the opaque upper layer and the lower layer.
