本文使用最新的渗透工具RFID飞贼(Tastic RFID Thief)和RFID感应破解技术来获取一些拥有安防的建筑物的访问权限. Tastic RFID Thief是一个无声远距离RFID读卡器,可不为人知地远距离盗取RFID信息,当不知情人员佩戴门禁卡或射频设备时,便会被它攻破.Tastic RFID Thief针对的是低频125KHz的射频系统,例如那些使用HID Prox或者Indala Prox的产品,不仅如此,你还可以利用它的电路板改造成一个13.56MHz的高频RFID读卡器,这…

RFID读写器的工作原理 RFID的数据采集以读写器为主导,RFID读写器是一种通过无线通信,实现对标签识别和内存数据的读出和写入操作的装置. 读写器又称为阅读器或读头(Reader).查询器(Interrogator).读出装置(Reading Device). 扫描器(Scanner).通信器(Communicator).编程/编码器(Programmer)等等. 读写器工作原理 RFID读写器的基本原理是利用射频信号与空间耦合传输特性,使电子标签与阅读器的耦合元件在射频耦合通道内进行能量传…

不同频段的RFID产品会有不同的特性,本文详细介绍了无源的感应器在不同工作频率产品的特性以及主要的应用. 目前定义RFID产品的工作频率有低频.高频和甚高频的频率范围内的符合不同标准的不同的产品,而且不同频段的RFID产品会有不同的特性. 其中感应器有无源和有源两种方式,下面详细介绍无源的感应器在不同工作频率产品的特性以及主要的应用. 1． 低频(从125KHz到134KHz)   其实RFID技术首先在低频得到广泛的应用和推广.该频率主要是通过电感耦合的方式进行工作, 也就是在读写器线圈和感应…
