The ACS ACR122U NFC USB Reader is a reliable, PC-linked contactless smart-card reader and writer based on 13.56 MHz RFID technology. Fully compliant with ISO/IEC 18092 (NFC) standards, it supports MIFARE®, ISO 14443 Type A/B cards, and NFC Tags Type 2–4, enabling broad interoperability with consumer and industrial NFC systems. With a high communication rate of 424 kbps and USB 2.0 full-speed (12 Mbps) interface, it ensures fast and stable data exchange. The built-in LED indicator and buzzer provide clear user feedback, while its anti-collision feature guarantees accurate tag reading. Compact and plug-and-play (CCID & PC/SC compliant), the ACR122U is widely used in e-payment, ticketing, access control, toll collection, and ID authentication systems. Its compatibility with GoToTags Desktop software also makes it ideal for high-speed NFC tag encoding and development purposes. Featured By RoboticsBD.
