Let me see.
1.) All government programs are expanded over time so one would have to be concerned with what info the chip will contain as well as how it can and will be used.

2.) With the expansion of the program private industry may seek to participate with their own needs for data thus expanding the data in the chip.

3.) Embedded chips will need a reader and readers can and will be acquired by those with no legitimate need leaving you exposed to identity theft and/or data manipulation.

4.) For the system to work everyone will need to receive a chip. You have to provide a negative (prohibitive person)as well as a positive (non prohibited person). An absence of a signal indicating a prohibited person can not mean “Ok to proceed”.

Just a few thoughts off the top of my head.
