A clasp can be included and configured to irremovably secure overlapping portions of the flexible band. The clasp can encase and protect the processor. The band cut detection system can comprise a detection application executable by a processor of a computer to receive and process the cut detection signal and responsively generate a cut detection indication. ## Claims ### Claim 1 A cut-detection identification band, comprising: a printable multilayer flexible laminated polyethylene film band having an end with an adhesive portion configured to overlap and permanently adhere to another portion of the band to form a loop around a wrist or ankle that is irremovable without tampering; a transmission medium extending at least 90% of a length of the band; a processor coupled to the transmission medium; a wireless communication device coupled to the processor; and a memory comprising detection logic executable by the processor to transmit a cut detection signal via the wireless communication device in response to a lack of continuity in the transmission medium, wherein the transmission medium, wireless communication device, processor and memory form part of an inlay antenna disposed between layers of the band. ### Claim 2 (depends on 1) The apparatus of claim 1, further comprising: a clasp configured to irremovably secure overlapping portions of the flexible band and the processor so that the clasp cannot be slid sideways relative to the band. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the clasp comprises a Bluetooth communication device secured to or integral with the clasp. ### Claim 4 (depends on 2) The apparatus of claim 2, wherein the clasp comprises a RF communication device secured to or integral with the clasp. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the transmission medium is a conductive medium or a fiber optic medium. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the processor, the inlay antenna, and the wireless communication device comprise a RFID (Radio Frequency Identification) device. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the inlay antenna is a Near Field Communication (NFC) inlay antenna. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the inlay antenna is a wet inlay antenna. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the inlay antenna is a dry inlay antenna. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein the memory further comprises identification information identifying a wearer of the identification band and/or of the identification band. ### Claim 11 (depends on 1) The apparatus of claim 1, wherein a cut or break in the transmission medium is processed by the processor as the lack of continuity in the transmission medium. ### Claim 12 (depends on 1) The apparatus of claim 1, wherein signal degradation over the transmission medium is processed by the processor as the lack of continuity in the transmission medium. ### Claim 13 (depends on 1) The apparatus of claim 1, wherein the cut detection circuit comprises one-time protection (OTP) logic configured to authenticate and enable the cut detection circuit. ### Claim 14 (depends on 1) The apparatus of claim 1, further comprising: a cut detection application executable by a processor of a remote device to: wirelessly communicate with one or more secure identification bands, and in response to a received cut detection signal from a secure identification band, generate a cut detection indication. ### Claim 15 (depends on 14) The apparatus of claim 14, wherein the cut detection indication includes an alert at the remote device. ### Claim 16 (depends on 14) The apparatus of claim 14, wherein the cut detection indication includes a transmission to an external monitoring system. ### Claim 17 A cut-detection identification band, comprising: a printable multilayer flexible laminated polyethylene film band having an end with an adhesive portion configured to overlap and permanently adhere to another portion of the band to form a loop around a wrist or ankle that is irremovable without tampering; an RFID inlay antenna extending at least 90% of a length of the band; and a cut detection circuit configured to generate a cut detection signal via the wireless communication device in response to a lack of continuity in the inlay antenna, wherein the RFID inlay antenna and the cut detection circuit are disposed between layers of the band. ### Claim 18 (depends on 1) The apparatus of claim 1, further comprising: a clasp configured to irremovably secure overlapping portions of the flexible band and the processor so that the clasp cannot be slid sideways relative to the band. ### Claim 19 (depends on 18) The apparatus of claim 18, wherein the clasp comprises a Bluetooth communication device secured to or integral with the clasp. ### Claim 20 (depends on 17) The apparatus of claim 17, wherein the cut detection circuit comprises one-time protection (OTP) logic configured to authenticate and enable the cut detection circuit.
