The ACR122U is a PC-linked contactless smart card reader/writer developed on the 13.56 MHz contactless technology. It is the world’s first
CCID-compliant contactless card reader/writer that follows both ISO 14443 and ISO 18092. This device is designed to support not only MIFARE® and ISO 14443 Type A and B cards but also FeliCa and NFC tags.
By making use of up to 424 Kbps read/write speed for NFC tag access and up to 12 Mbps for USB full speed, ACR122U can efficiently read from and write to various contactless cards/tags. It is also PC/SC-compliant which allows interoperability across different applications and platforms.
You can experience the convenience in using ACR122U, with its compact size and the various features it offers, for applications such as payment, access control, time and attendance, and mass transit.

Today, the use of radio frequency identification (RFID) technology in the apparel industry is becoming more common, opening up a range of exciting opportunities for innovation for apparel manufacturers and retailers. As small, smart devices, RFID tags have found a variety of applications on clothing, bringing many benefits to consumers, retailers and manufacturers.
Radio frequency identification (RFID), a non-contact automatic identification technology. It mainly consists of tag, reader, antenna, processing terminal hardware and software. Inductive coupling. The transformer model, coupled by a space…
In recent years, RFID iButton technology has been widely used in supply chain management, from retail to manufacturing industries. RFID iButton is a type of radio-frequency identification (RFID) technology that allows companies to track and manage their inventory and assets with greater efficiency and accuracy. In this article, we will explore the role of RFID iButton in revolutionizing supply chain management, and the benefits it offers to businesses.
Radio frequency identification (RFID) technology is a wireless communication technology that can transmit data through radio frequency signals between electronic tags (also known as RFID tags or RFID tags) and readers. Ultra High Frequency (UHF) RFID tags are a specific type of RFID tags that typically operate at frequencies between 860 MHz and 960 MHz.
Tracking and traceability are essential for suppliers in today’s fast-paced and highly-competitive business environment. RFID ear tags have emerged as a powerful tool for suppliers to improve their supply chain management and ensure the safety and quality of their products. In this article, we will discuss the importance of RFID ear tags for suppliers and how they can be used to improve tracking and traceability in the supply chain.
