Silicon Craft RFID, NFC & Sensor Interface Chips

Silicon Craft Technology is a Thai fabless IC design company founded in 2002 by Thai researchers and electronic engineers, headquartered in Bangkok and listed on the Thai stock exchange. It designs RFID and NFC microchips that let manufacturers identify, authenticate and track animals, vehicles, products and industrial assets.

Its product lines include LF HDX and FDX-B transponders for animal identification, immobilizer transponders for cars, multi-protocol HF reader ICs, ISO/IEC 15693 tag ICs, advanced NFC tag ICs with energy harvesting and web authentication, and sensor interface chips for conductivity, biosensor and electrolyte measurement. It also offers custom ASIC design and works with foundries and OSATs for production.

• Animal ID transponders: LF HDX and FDX-B chips for livestock and pet identification.
• Immobilizer transponders: chips for automotive anti-theft key systems.
• HF reader ICs: multi-protocol high-frequency reader chips.
• Advanced NFC tags: tag ICs with energy harvesting and web authentication.
• Sensor interface: chips for conductivity, potentiostat biosensor and electrolyte sensing.
• ASIC design: custom and standard-cell IC design services.

A Vietnamese livestock or pet tag maker can build ear tags and microchips on the company's animal ID transponders. A consumer goods exporter can add NFC authentication tags to packaging for anti-counterfeiting and product passports. A medical device startup can use the sensor interface chips in handheld biosensor readers.

Provides off-the-shelf RFID and NFC chips for tag, reader and module makers, backed by more than 20 years of design experience. NFC tag ICs with energy harvesting allow battery-free sensing and smartphone control. Web authentication NFC chips support brand protection against counterfeits. Sensor interface chips reduce the component count of biosensor and conductivity measurement devices.

Traceability rules for livestock, food and consumer goods, and the coming Digital Product Passport requirements for exports to Europe, are increasing demand for RFID and NFC tags. Southeast Asian manufacturers also want authentication against counterfeits, which favours regional chip suppliers with application support.

Founded in 2002 in Thailand; headquarters in Chatuchak, Bangkok; listed as a public company on the Thai stock exchange. Named in Forbes Asia's Best Under a Billion 2024. Its RFID TrustLink won a Performance Efficiency Excellence Award at the Thailand Cybersecurity Product and Service Awards 2025.
