Performance is a key strength of this HF RFID desktop reader. The ACR122U delivers smart card read/write speeds of up to 424 Kbps and an operating distance of up to 50 mm, enabling fast, convenient, and reliable contactless transactions. Its built-in anti-collision technology ensures that only one card or NFC tag is processed at a time, preventing data conflicts and guaranteeing operational accuracy in high-throughput environments. Integrated visual and audio feedback — a user-controllable bi-color LED and buzzer — provide clear confirmation of successful reads and transactions, improving the overall user experience. The reader is powered directly via USB, eliminating the need for an external power supply and simplifying both fixed and mobile deployments. Its slim, pearl-white housing measures just 98 × 65 × 12.8 mm and weighs only 70 g, making it an ideal fit for desks, service counters, kiosks, and embedded system setups where space and aesthetics matter.
