The ACR122U NFC Reader is a PC-linked contactless smart card reader/writer developed on the base of 13.56 MHz contactless technology. Compliant with the ISO/IEC18092 standard for NFC, it supports all four types of NFC tags. ACR122U is compliant with both CCID and PC/SC. Thus, it is a plug-and-play USB device allowing interoperability with different devices and applications. With an access speed of up to 424 kbps and a full USB speed of up to 12 Mbps, it can also read and write more quickly and efficiently. The proximity operating distance of ACR122U is up to 5 cm, depending on the type of contactless tag in use. The ACR122U NFC reader is ideal for both secure personal identity verification and online micro-payment transactions.<!--Features --><p>FEATURES</p><ul><li> Identity verification, data exchange & contactless transaction</li><li> Support different OS</li><li> USB 2.0 full speed interface</li><li> Read/write speed up to 424 kbps</li><li> Built-in antenna for contactless tag access, with card reading distance of up to 50mm</li><li> Support ISO 14443 type A and B cards, for smart card reader, FeliCa, and all 4 types of NFC (ISO/IEC 18092) tags</li><li> Built-in anti-collision feature</li><li> Support PC/SC</li></ul><!--Specifications --><p>Specifications</p><table width="100%" border="0" cellpadding="0" cellspacing="0"><tbody><tr><td width="131"> Shell Dimensions</td><td width="365"> (3.86 x 2.56 x 5.04)" / (9.8 x 6.5 x 12.8)cm (L x W x H)</td></tr><tr><td width="131"> Weight</td><td width="365"> 2.47oz / 70g</td></tr><tr><td width="131"> Interface</td><td width="365"> USB High Speed</td></tr><tr><td width="131"> Voltage</td><td width="365"> Rated Voltage 5V DC</td></tr><tr><td width="131"> Current</td><td width="365"> 200mA (Working); 50mA (Standby); 100mA (Normal)</td></tr><tr><td width="131"> Working Temperature</td><td width="365"> 0-50→</td></tr><tr><td width="131"> Working Frequency</td><td width="365"> 13.56 MHz</td></tr><tr><td width="131"> Support</td><td width="365"> ISO 14443 Type A and B Cards, for Smart Card Reader, FeliCa, and All 4 types of NFC (ISO/IEC 18092) Tags</td></tr><tr><td width="131"> Operating System</td><td width="365"> Windows 98/ME/2000/2003/XP/Vista/2008/7 ; For Windows 2003 x64, XP x64, Vista x64, 2008 x64, 2008 R2 x64, 7 x64 ; For Windows CE 5.0 ; For Mac Linux</td></tr><tr><td width="131"> Color</td><td width="365"> White</td></tr><tr><td width="131"> Material</td><td width="365"> Plastic</td></tr><tr><td width="131"> Operating Frequency</td><td width="365"> 13.56MHz</td></tr><tr><td width="131"> Read/Write Speed</td><td width="365"> Up to 424 kbps </td></tr></tbody> </table><!--Package Includes --><p>Package Includes</p><ul><li>1 x ACR122U NFC Contactless Smart Card Reader & Writer</li></ul><!--Extra Info --><!--produts_compatibility -->
