Smart Cards New Technology for Producing RFID Inlays by 70Khz Ultrasonic Wire Embedding Machine Radio frequency identification (RFID) inlays are manufactured throughout the world for many purposes: biometric passports, the contactless smart card market (e-ID, electronic healthcare cards, payment cards, public transportation), and for dual interface applications. At the same time, wire-embedded high frequency (HF) RFID antennas are available and offer a number of advantages over printed, etched, or galvanized variations. Among others, the ability to freely select shapes is enticing for card and passport manufacturers, since this can lead to competitive advantages. Further benefits, such as environmental friendliness, durability, and improved product quality, also should be mentioned.
