Fingerprinting required by banks

Regarding a power source for biochips, I have firsthand experience
with this technology, specifically the microwave transponder
identification chip from Proximity Technologies. I worked on a project
that used this chip in a plactic credit card sized carrier in 1988.

These devices are "pumped" by an external microwave radiation source.
The power from this radiation is picked up by a short antenna a couple
of inches long, and then rectified, filtered, and used to power the
chip.  When the chip receives power, it generates a different
microwave carrier frequency which is digitally modulated with a unique
identification code.  The reader then receives this modulated
transponder signal and validates the ID code it contains.

The reader for these chips may be up to 6 feet away, and the card does
not need to be removed from the person's wallet to be read.  All the
person does is walk past the reader, which is typically behind drywall
and invisible, and the doors open.  When someone without a valid card
walks up, the doors will not open.

This chip is suitable for use as an implant, since no external power
connection needs to be made.  The antenna wire can be made of the same
material as pacemaker wires, and the chip itself is passivated
silicon.  It was not being marketed as an implant at that time.

I only found a single reference to the company online, and it was in a
list of hi-tech firms, but the listing for Proximity Technologies only
said that it was not yet listed.  Oh well...
