将μ-Chip嵌入入场券中,由于其只读的特性,可避免信息被复制到同样的μ-Chip芯片上,真正实现了每张入场券被赋予一个唯一的识别码,起到有效的防伪作用。而可读可写的芯片理论上是可复制的,而且为了防止非法读写,可读可写的芯片需要不断提高保密等级从而不断增加芯片的单价成本,但事实上,又并不能从根本上解决随时被...
Data encoding refers to processing or altering the data bitstream in-between the time it is retrieved from the RFID chip’s data array and its transmission back to the reader. The various encoding algorithms affect error recovery, cost of implementation, bandwidth, synchronization capability and ot...
