Miniaturized HF RFID Antennas for Contactless Payment Devices

Contactless payment systems are becoming an increasingly important part of our daily lives. With IoT applications, means of payment can have several physical representations. One of the most common is the bank card. This article presents a typology of antenna that can respond to several contactless payment device form factors (bank card, wearable, IoT device, etc.). the proposed miniaturized antenna allows, once assembled, to provide contact and contactless payment facilities without the addition of additional larger antennas which significantly reduces manufacturing costs. Modeling, integration and validation in a normative context is presented.
