Dual-mode RFID devices are provided with an integrated dual-mode RFID strap including either a UHF/HF dual-mode RFID chip or the combination of a UHF RFID chip and an HF RFID chip. An HF antenna and a UHF antenna are both coupled to the integrated dual-mode RFID strap, with the UHF antenna being formed by an approach other than etching, such as a cutting or printing operation, thereby reducing the cost to manufacture the device. If a pair of chips is employed, one of the chips may have a greater thickness than the other chip, which allows for the thicker chip to be incorporated into the device after the thinner chip without requiring a minimum separation between the two chips due to the size of a thermode used to secure the chips. Additionally, the first chip may be tested before securing the second chip, thereby limiting the cost of a rejected device.
