A dual security tag including an RFID component and an electronic article surveillance (EAS) component, respectively disposed on opposite sides of a PET carrier substrate, is provided. The RFID component may include one or more ultra-high frequency antennae, such as a near field loop antenna and a far field dipole antenna, and an integrated circuit (IC) chip. The EAS component may be provided as an RF device, an acoustic-magnetic (AM) device, a low power Bluetooth (BLE) device, or other suitable device. The security tag may also include a facesheet affixed to the RFID component, a release liner layer affixed to the EAS device, and one or more intermediary films or protective layers. A method for manufacturing a dual security tag is also described.
A dual-purpose security label comprising:
A combination radio frequency identification (RFID) and electronic article surveillance (EAS) tag comprising:
A security tag comprising:
The security tag of 18, wherein the shape of the shielding bar is U-shaped.
The security tag of 17, wherein the shielding bar is a first shielding bar, and wherein the security tag further comprises a second shielding bar disposed on the second side of said carrier substrate.
The security tag of 17, wherein the shielding bar presents a constant impedance to the UHF antenna of the RFID component.
