Tim,
That depends on what tag you are going to use. The Class I tag has 96 bits
of memory that can be programmed. There are some types of tags that have the
ability to password protect the memory, but when you do things like that it
drives the price up. The tags can be written, but I doubt you will be able
to pull the original data off once it's erased since it's stored on the
tag's chip.

Hi,
Does anyone have information / experience on how secure these tags are? Can
the data they store be changed in anyway? Can they be copied / faked? If
they are changed can the original information still be read?
Cheers
Tim
