AI Overview
Ultrasonic inlay winding coils are specialized components, primarily used for antennas in contactless smart cards, RFID wristbands, and key fobs. High-frequency (often 70 kHz) ultrasonic technology embeds copper wire directly into materials like PVC, enabling faster, automated production for dual-interface bank cards and RFID inlays.
