"You say now that they have a scanner replacing a human?"

You need to come into the 21st century.
To answer your question, YES.

"The only benefit I see that having a chip within a chip will do is to verify that the chip is not a counterfeit"

You are not seeing far enough.

Big Brother has arrived at the casino's. Mikohn and Mind Play are only the 1st generation of these systems. Mind Play is going into several CA indian casinos in the next few months, 5 or 6 if I remember right. I think the Mohican Sun is going to use it also. There are no tracking chips in MP chips like Mikohn uses and they still do the job. MP chips are still around $1.

Remember I said 1st generation. I believe both systems will go obsolete soon unless they keep up with the other new ones coming on line.
