NFC

Giantec combines non-volatile memory (NVM) and mixed-signal technologies with downstream identification and contactless communication applications. Based on broad interoperability and practical security, we have developed a series of NFC chip products.These chips support passive (battery‑free) operation, touch‑to‑transfer functionality, and require no manual pairing. They feature multiple security mechanisms including password protection, lock bits, and optional authentication, ensuring high security and confidentiality. An embedded non‑volatile memory stores fixed identification codes and application data, and customers can perform on‑site configuration updates, feature activation, and after‑sales support via NFC‑enabled devices.


Based on protocols such as ISO/IEC 14443 and 15693, Giantec’s NFC chips have achieved domestic leading performance in minimum operating field strength, ultra‑low power consumption, and embedded non‑volatile memory characteristics. The products are widely used in consumer electronics, smart homes, wearable devices, electronic shelf labels, packaging accessories, and industrial facilities.
