## Abstract

An RFID with uniform profile. A compressible mask layer or cutout mask layer provides a uniform profile despite the presence of an RFID integrated circuit and antenna. The uniform profile allows clear overprinting and hinders visual detection of the RFID transponder.

## Claims

### Claim 1

An RFID Label comprising:
a facesheet,
a RFID Transponder,
a mask with RF Transponder sized cut out,
a liner,
an adhesive,
said facesheet applied with said adhesive to said mask, said RF Transponder positioned within said cut out, said mask having adhesive thereon attached to a liner for protecting said adhesive until use.

### Claim 2 (depends on 1)

The RFID label of claim 1, wherein;
said mask is a high intensity open-celled urethane material.

### Claim 3 (depends on 1)

The RFID label as claimed in claim 1, wherein;
said mask is a closed cell vinyl material.

### Claim 4 (depends on 1)

The RFID Label as claimed in claim 1, wherein;
the label is linerless.
