The ACR122U is a complete solution for communication with NFC tags and contactless cards. It operates at a frequency of 13.56 MHz and offers access speeds of up to 424 kbps, ensuring instant reading and writing of data. Thanks to its compliance with the ISO/IEC 18092 standard for Near Field Communication (NFC), it is compatible not only with traditional RFID cards but also with mobile phones equipped with NFC technology, expanding its range of applications.

This smart reader supports a wide range of card types, including ISO 14443 Type A & B, MIFARE, FeliCa, and all four types of NFC tags (ISO/IEC 18092). Whether it is simple sticker tags or complex security cards, the ACR122U can manage their information accurately. The reading distance reaches up to 50 mm (depending on the type of tag), offering convenience of use without the need for direct contact.

The device connects easily to any computer via a USB Full Speed port. It is fully compatible with the CCID (Chip Card Interface Device) standard, which simplifies installation as the drivers are automatically recognized by most operating systems. Integration into existing IT systems is seamless, while power is supplied directly from the USB port, eliminating the need for external power supplies or batteries.

To enhance the user experience, the ACR122U features a built-in Buzzer and a dual-color LED indicator. These elements provide immediate visual and audio feedback for the successful reading or writing of a card, making it ideal for points of sale or access control gates. Additionally, the device includes an anti-collision function, which allows the detection of a specific card even when multiple cards are presented to the reader simultaneously.

The ACR122U is the favorite tool of developers worldwide, as it supports the PC/SC standard. This allows the creation of specialized applications for e-payment, electronic ticketing, network access control, or even customer loyalty programs. Its robust construction and reliability make it a long-term investment for any business wishing to integrate contactless technologies into its services.

With exceptionally small dimensions (98 mm x 65 mm x 12.8 mm) and a weight of only 70 grams, the reader takes up minimal space on your desk. Its minimalist design in white matches any professional environment, while the 1.0m cable provides the necessary flexibility for its placement. It is a high-aesthetic device that combines advanced NFC technology with everyday practicality.
