GSN22 is Goodix’s NFC chip delivering high security, high performance, and multi‑functionality. It integrates NFCC and eSE and supports small or single‑ended antennas, making it ideal for space‑constrained devices.
The NFCC features excellent RF performance and strong anti‑interference, with a built‑in NFC protocol stack compliant with NFC Forum and EMVCo standards. The eSE integrates the GRACE cryptographic accelerator, supports multiple international security algorithms, and runs on Goodix’s self‑developed COS. Both the IC and COS are CC‑certified.
GSN22 enables contactless smart devices—such as digital car keys, smartphones, wearables, and hardware wallets—and supports GCF and EMVCo certification.
