Who’s going to get an implantable RFID chip?
[quote=Pete In Florida]
I’ve worked on RFID circuits for the past few years.
Scary, scary stuff.
Perfect for chipping packages, livestock, sheep, but not people that are not sheep.
It’ll be sold as the greatest thing since Moses coming down from the mountain.
As you are aware RFID devices (not the readers) are very simple and cheap to produce.
They can be in the form of a card, tag, key-fob, embedded microchip or human implantable microchip.
They only comprise a single microchip and small coil (antenna) and essentially are a passive device not requiring any internal hardwired power source.
But they do require power in order to transmit the ID code back to the scanner.
For those that may wonder how an RFID microchip is powered when it has no hardwired power source, it works like this.
When out of range of a scanner the RFID microchip is dormant and non-functional.
It is the scanning device that is powered and transmits an electrical Radio Frequency (RF) signal.
When the the RFID device comes within range of a compatible scanner the RFID device receives its power from the RF (radio frequency) field generated by the scanner which is induced in the coil or antenna of the RFID device.
Thus it is the scanner’s RF energy field that actually powers the RFID microchip when in range of the scanner. The now active RFID device then transmits its unique ID code back to the scanner which is read and linked to a database.
At the present only a coded number is stored in the RFID device.
The relevant information is located elsewhere on a computer database.
Of course, as long as you have aluminum foil, your chip can be made non-responsive..
SG … yeah a good use for our tinfoil hats . Tell us how we best use them . I better get one in my GOOD bag !!
I really could use some positive news from somewhere today .
