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.

Process for manufacturing a chip-card module. It includes one or more operations in which a meltable solder is deposited on connection pads formed in a layer of electrically conductive material located on the back side of a dielectric substrate, and at least one electronic component is connected to these connection pads by reflowing the solder. Chip-card module obtained using this process. Chip card including such a module.

A wireless connection is established between at least two electronic modules (M1, M2) disposed separate from one another in a smartcard having a coupling frame so that the two modules may communicate (signals, data) with each other. The two modules may each have module antennas (MA-1, MA-2), and may be disposed in respective two openings (MO-1, MO-2) of a coupling frame (CF). A coupling antenna (CPA) having two coupler coils (CC-1, CC-2) disposed close to the two modules antennas of the two modules. The coupling antenna may have only the two coupler coils (CC-1, CC-2), connected with one another, without the peripheral card antenna (CA) component of a conventional booster antenna (BA). Energy harvesting is disclosed.
