ST25R3916B: New NFC reader accelerates payment, consumer and industrial application designs

The ST25R3916B is a high-performance NFC universal device supporting NFC initiator, NFC target, NFC reader and NFC card emulation modes when applicable.

It can be used in contactless payment, device-pairing, wireless-charging, brand protection, and other industrial and consumer applications.

Fully compliant with EMVCo 3.1a analog and digital, this NFC IC is optimized for POS terminal applications, and enables fast EMVCo certification cycles, even under harsh conditions (e.g., antenna placed near noisy LCD displays).
