常称为感应式电子晶片或近接卡、感应卡、非接触卡、电子标签、电子条码，等等。

一套完整 RFID系统由 Reader 与 Transponder 两部份组成 ,其动作原理为由 Reader 发射一特定频率之无限电波能量给Transponder,用以驱动Transponder电路将內部之ID Code送出，此时Reader便接收此ID Code。

Transponder的特殊在于免用电池、免接触、免刷卡故不怕脏污，且晶片密码为世界唯一无法复制，安全性高、长寿命。

RFID的应用非常广泛，目前典型应用有动物晶片、汽车晶片防盜器、门禁管制、停车场管制、生产线自动化、物料管理。

RFID标签有两种：有源标签和无源标签。

以下是电子标签内部结构:芯片+天线与RFID系统组成示意图2．什么是电子标签电子标签即为 RFID 有的称射频标签、射频识别。

它是一种非接触式的自动识别技术，通过射频信号识别目标对象并获取相关数据，识别工作无须人工干预，作为条形码的无线版本，RFID技术具有条形码所不具备的防水、防磁、耐高温、使用寿命长、读取距离大、标签上数据可以加密、存储数据容量更大、存储信息更改自如等优点。

Operation is subject to the following two conditions:(1) This device may not cause harmful interference, and(2) This device must accept any interference received, including interference that may cause undesired operation.Connecting the DeviceThe BF-IDU08 device has to be connected to one of the IO-Link-Device ports of an IO-Link-Master unit via standard 4-wire cable with M12 industry connectors (A-coded). The IO-Link-Master unit provides power supply and controls the device over its IO-Link interface connection.Figure 1: System overviewThe IO-Link-Master unit itself needs to be connected to a power supply and the customer's PLC unit. For further information, please refer to the user manual of the used IO-Link-Master unit. MountingBefore operating the device has to be mounted with the provided M30 nuts or other suitable fixtures, Figure 2. Optional mounting fixtures are available at .The BF-IDU08 device may be mounted in any direction, the operating direction of the integrated antenna is towards the length axis of the BF-IDU08 device as displayed in Figure 1 (direction towards the UHF-Tags).Figure 2: BF-IDU08 mounted on metal carrier using 2 x Nut M30The antennas of the identification system BIS U transmit ultra-high frequency electromagnetic waves. People should not remain within the near enclosure of the UHF antenna over long time periods (several hours). The mounting position of the BF-IDU08 should take respect to a clearance area of about 25cm to workplaces.Setup and OperationThe BF-IDU08 device will operate when connected to an IO-Link-Master that provides power supply and implements the BF-IDU08 RFID-Reader protocol.Device behavior e.g. transmission power or operating modes can be setup via different parameters. Protocol description and available parameters are described in the firmware configuration manual.Status IndicatorsThe device will show its status using RGB LEDs located at the M12 plug. Depending on the device state the LED changes color and lighting mode (static, blink slow, blink fast).Electrical DataMechanical Data。

1、UHF RFID读卡实验1.1、EPC Gen2读、写标签号实验实验目的理解UHF RFID的工作原理，并掌握其与HF RFID工作原理的异同点。

掌握EPC标签号的存储区域以及结构特点。

实验设备UHF 读卡器一个、UHF 天线一个、USB连接线一条、9V电源适配器一个、电脑一台、UHF实验上位机软件实验知识预备与原理1.UHF-RFID工作原理在UHF RFID阅读器及电子标签之间的通讯是采用电磁反向散射耦合方式完成。

电磁反向散射耦合方式类似雷达的工作原理，如下图所示。

阅读器就像手电筒，标签就像一个镜子，标签反射最大，就是逻辑“1”。

标签反射最小，就是逻辑“0”。

阅读器开始工作之后，通过天线先向空间发送860～960 MHz频率范围的载波，激活标签，然后开始发送带调制的命令信息到标签（TAG），可以采用ASK调制，脉冲间隔编码（Pulse Interval Encoding），通讯速率26.7到128 KBIT/S。

在高频范围内的标签收到阅读器发出的高频载波信号，标签天线接收到特定的电磁波，天线就会产生感应电流，在经过整流电路时，激活电路上的微型开关，给标签供电。

标签上的电子线路，将根据阅读器发出信息，通过ASK或者PSK 耦合方式进行调制，FM0等编码方式，向阅读器反馈相关信息。

UHF标签电路采用ASK和PSK的调制方式，将编码信息发送给阅读器，实现了阅读器和标签之间的双向通讯。

相互认证通过之后，阅读器会向电子标签发出读、写、锁定、kill、盘存等操作指令。

2.EPC编码产品电子代码(EPC编码)是国际条码组织推出的新一代产品编码体系，原来的产品条码仅是对产品分类的编码，EPC码是对每个单品都赋予一个全球唯一编码，EPC编码96位(二进制)方式的编码体系，可以为2.68亿公司赋码，每个公司可以由1600万产品分类，每类产品有680亿的独立产品编码，形象的说可以为地球上的每一粒大米赋一个唯一的编码。

UHF-RFID基础知识符合EPC Class1 Gen2（简称G2）协议V109版的电子标签（Tag，简称标签）和Reader（读写器）,应该具有下述的特性。

Q1：标签存储器分为哪几个区？A：Tag memory（标签内存）分为Reserved（保留），EPC（电子产品代码），TID（标签识别号）和User（用户）四个独立的存储区块（Bank）。

Reserved区：存储Kill Password（灭活口令）和Access Password（访问口令）。

EPC区：存储EPC号码等。

TID区：存储标签识别号码，每个TID号码应该是唯一的。

User区：存储用户定义的数据。

此外还有各区块的Lock（锁定）状态位等用到的也是存储性质的单元。

Q2：标签有哪几种状态？A：收到连续波（CW）照射即上电（Power-up）以后，标签可处于Ready（准备），Arbitrate（裁断），Reply（回令），Acknowledged（应答），Open（公开），Secured（保护），Killed（灭活）七种状态之一。

1、Ready状态是未被灭活的标签上电以后，开始所处的状态，准备响应命令。

2、在Arbitrate状态，主要为等待响应Query等命令。

3、响应Query后，进入Reply状态，进一步将响应ACK命令就可以发回EPC 号码。

4、发回EPC号码后，进入Acknowledged状态，进一步可以响应Req_RN命令。

5、Access Password不为0才可以进入Open状态，在此进行读、写操作。

6、已知Access Password才可能进入Secured状态，进行读、写、锁定等操作。

7、进入到Killed状态的标签将保持状态不变，永远不会产生调制信号以激活射频场，从而永久失效。

被灭活的标签在所有环境中均应保持Killed状态，上电即进入灭活状态。

灭活操作不可逆转。

要使标签进入某一状态一般需要适当次序的一组合法命令，反过来各命令也只能当标签在适当的状态下才能有效，标签响应命令后也会转到其他状态。

RFID标签和读卡器介绍说明作为在供应链上跟踪产品的一种手段，RFID在访问控制和越来越多的传统应用(如售票)中迅速得到采用。

RFID系统一般由单芯片RFID标签和一个RFID读卡器组成，标签上集成了射频前端、存储器和控制器，RFID读卡器可对标签上的数据进行解码，然后进行适当的操作(比如打开门锁)。

RFID标签类似于条形码，但它们是以电子方式存储产品信息。

最新的RFID标签除了具有安全特性外，还具有随着产品在供应链上传输，自动更新相关信息的能力。

RFID标签可用于跟踪从家庭宠物、家畜到高端电子产品的所有物品。

它们可以自动征收过桥费和道路费，可以限制接近敏感区域。

最近，RFID标签开始进入安全性更高的领域，如制药、无接触支付、货运安全以及电子护照等。

这些信息应用和安全密集型应用必须采用新的标准来定义RFID标签和读卡器。

这种标准包括：标签上存储器的可用性、加密算法的鲁棒性、标签上不同信息区的数目和安全性。

存储密度和配置能力RFID标签必须能够支持更精确的跟踪机制。

以制药业为例，据美国食品与药品管理局(FDA)统计，假药的数量在过去5年中增加了10倍。

在最坏的情况下，假药甚至可能危及病人的生命。

制造商在药片上的标记可被逼真地复制，达到以假乱真的效果。

包装上的条形码虽然可以提供一些额外的信息和安全措施，但也很容易被扫描和复印。

估计全球有10%的处方药是假药，每年因此而无辜丧失的生命数以万计。

为阻止假药泛滥，美国佛罗里达州规定，从2006年7月1日起，处方药必须具有纸面的药历档案，包含药品的名称、剂量表、浓度、制造商、批号数量、相应的发票/付运/转账凭单号、交易日期、每一位所有者的名称和地址、每一位用药者的名称和地址、鉴定证书、每一位批发商的联络信息、确认该药历档案信息准确完整性的签名或宣誓，以及制造商的跟踪号码等信息。

美国加利福尼亚州要求从2009年1月1日起，药品必须具备电子药历档案，其它各州也将纷纷效仿。
