摘要： Methods, systems, and apparatuses for preventing unauthorized reading of data stored in tags (700) are described. A non-identifying bit pattern (702), an identifying bit pattern (710), and a first passcode (712) are stored in the tag. A read lock command is received by the tag. The tag determines whether a second passcode associated with the read lock command matches the first passcode. Read access to the identifying bit pattern is disabled if it is determined that the second passcode matches the first passcode.
摘要翻译：描述了用于防止未经授权的读取存储在标签（700）中的数据的方法，系统和装置。在标签中存储非识别位模式（702），识别位模式（710）和第一密码（712）。标签接收到读取锁定命令。该标签确定与读取锁定命令相关联的第二个密码是否与第一个密码相匹配。如果确定第二个密码与第一个密码相匹配，则对该识别位模式的读访问被禁用。

摘要： Methods and apparatuses for secure communications of confidential information are provided. In an embodiment, a method of communicating with a population of radio frequency identification tags includes transmitting a first interrogation signal, receiving a response to the first interrogation signal from at least one RFID tag at a first received signal strength including at least a portion of a first identification code, and transmitting a second interrogation signal that includes a request for confidential information, a command to transmit a response to the second interrogation signal at a secure power level, and the first identification code. In another embodiment, a method for communicating with an RFID tag includes receiving an interrogation signal that includes a request for confidential information and transmitting a response to the interrogation signal at a secure power level. The response includes the confidential information.

摘要： Methods, systems, and apparatuses for testing antenna(s) of a radio frequency identification (RFID) tag are described. A reader transmits a test command signal to a RFID tag having a plurality of antennas. Each antenna of the plurality of antennas is coupled to a respective antenna port. The tag processes the test command signal to determine which one or more of the plurality of antennas is to be tested. The tag couples an information signal to the antenna port(s) corresponding with the antenna(s) to be tested. For example, the tag may include enabling elements that selectively couple the information signal to respective antenna ports based on respective test control signals. The RFID tag generates the test control signals based on the test command signal. The reader awaits receipt of the information signal from the RFID tag.
摘要翻译：描述了用于测试射频识别（RFID）标签的天线的方法，系统和装置。读取器将测试命令信号发送到具有多个天线的RFID标签。多个天线中的每个天线耦合到相应的天线端口。标签处理测试命令信号以确定要测试多个天线中的哪一个或多个。标签将信息信号耦合到与要测试的天线对应的天线端口。例如，标签可以包括基于相应的测试控制信号选择性地将信息信号耦合到各个天线端口的使能元件。 RFID标签根据测试命令信号产生测试控制信号。读者等待从RFID标签接收信息信号。
