摘要
近场通信是继蓝牙、Wi Fi、ZigBee后的又一种短距离无线通信技术,它以射频识别技术为基础,允许设备之间进行非接触点对点数据传输和数据交换。为促进该技术的发展,恩智浦公司推出了PN511系列芯片,该系列芯片支持读写器、卡模拟以及点对点三种不同应用模式,并可根据应用需求在不同模式间切换。此外近场通信技术还具有带宽高、功耗小、成本低以及良好的安全性等特点,在手机支付等领域具有广阔的应用前景。
Near field communication is another kind of short distance wireless communication developed after Bluetooth, Wi-Fi, ZigBee. It bases on the radio frequency identification technology, t allows non-contact point-to-point data interchange and data transmission between devices. In order to promote this technology, a series chip of PN511is produced by NXP. These chips support reader-writer mode, card emulation mode and point-to-point mode. It can switch modes according to the demand of application. In addition, near field communication technology also has many features, such as high bandwidth, low power consumption, low cost and good security. It has a broad application prospects in the field of mobile phone payment.
