NFC/RFID ICs, modules and short-range communication solutions

About the manufacturer

3ALogics Inc. is a South Korean semiconductor company specializing in NFC and RFID technologies. Founded in 2004, it focuses on the design of integrated circuits, modules and complete short-range wireless communication solutions. The manufacturer increasingly positions its NFC technologies alongside IoT functions and on-device solutions.

The core portfolio includes NFC Reader ICs, NFC Tag ICs and reader modules operating at 13.56 MHz. 3ALogics also offers NFC tags and labels, development kits, and solutions based on dynamic and passive NFC tags. Its technical materials also cover multi-band reader concepts and designs that combine NFC with microcontroller interfaces, sensors and memory.

An important application area is identification, authentication and short-range data exchange without conventional wired interfaces. The company also identifies automotive applications, including vehicle-access systems, and develops NFC Wireless Charging solutions intended for low-power devices.

3ALogics supplies both standalone ICs and modules or evaluation kits, making its products relevant from early prototyping through OEM design and series production. Its solutions are aimed mainly at electronics designers, system integrators and manufacturers that need NFC/RFID connectivity in embedded products.

Applications

The manufacturer’s products and technologies are used in areas including:

Access-control systems – electronic locks, credential readers and entry/exit terminals.
Identification and authentication – confirming users, products or accessories with NFC/RFID.
Consumer electronics – portable devices, accessories, smart-home equipment and products with tap-based interfaces.
Internet of Things (IoT) – configuration, service and data exchange with NFC-enabled devices.
Automotive – vehicle access, identification and short-range communication functions.
Logistics and product identification – tagging, tracking and storing information directly in tags.
Measurement and sensing devices – reading data from sensors or loggers equipped with NFC.
Low-power wireless energy transfer – applications using NFC Wireless Charging.
