There is a USA based company called Applied Digital Solutions which seems to be intent on selling the creepiest and most threatening versions of RFID tags - ones which are implanted under the human skin.
These VeriChips work on 125KHz which copes better than the High Frequency 13.56MHz or Mobile Phone frequency range (868 - 930 MHz) Ultra High Frequency RFID tags, with absorbtion by the mostly saline liquid human body. Their range is limited, but seems to be sufficient for door scanners.Naturally, although these RFID tags contain a unique serial number, this is not compliant with even the weak EPCglobal standards for privacy, and they are too "stupid" to be "killed" or decativated even temporarily. Obviously removal of the tags requires another surgical operation.
These so called "security" chips are the 21st century version of permanent cattle brands (indeed the original market for Verichips is for prize cattle and pet cats and dogs) or tattoos.
We find the concept completely unethical, bordering on actually evil. What is there to prevent this technology being used by exploiters of slave labour, pimps and brothel keepers, religous cults, abusive or paedophile parents or police states in order to control the movements of their victims and to prevent escape via actual alarm systems or the fear that "we will track you down if you try to escape" ?
They are being sold to the Latin American and Russian markets, aimed initially to exploit the fears of rich parents who fear that their children may be kidnapped, and who are therefore willing to electronically brand them in the vain hope that this will somehow make it easier to trace kidnap victims.
The alternative market to the forced branding of children who are in no position to object is to electronically brand vulnerable adults, e.g. those with Alzheimer's disease, again, a process likely to happen without fully informed consent. The company is also selling the concept of access to online medical records via the VeriChip RFID serial number.
If we have expressed doubts about the security and privacy implications of the EPCglobal back end "internet of things" databases, then these worries are multiplied by orders of magnitude when it comes to VeriChip databases containing details of children or vulnerable adults with, in some cases their online medical records.
The VeriChip distributor in Mexico Solusat, is proudly claiming links with the Mexican Red Cross for access to Medical Records, and the National Foundation of Investigations of Robbed and Missing Children
Why then, is Solusat not using SSL/TLS session encryption on the website through which the VeriChip RFID tag registration details and medical records can be accessed ?
Why is the SQL Server administrator account and password apparently visible to any hacker or corrupt employee, simply by inspecting the HTML source code of this website ?
This would be bad enough if the only thing that they were putting at risk was credit card details, but to put Children's details and Medical Records at risk over the internet or to corrupt employees in this way is criminal negligence.
The latest nonsense from the company is VeriPay, an attempt to try to convince people that electronic payments could be safely authorised using their crude technology which does not employ encrypted authentication handshakes, instead of a normal credit card.
Of course, many fundamentalist Christians see RFID technology, but especially VeriChips as the "Mark of the Beast":
"Moreover, it caused everyone, great and small, rich and poor, slave and free, to be branded with a mark on his right hand or forehead, and no one was allowed to buy or sell unless he bore this beast's mark, either name or number. (Here is the key; and anyone who has intelligence may work out the number of the beast. The number represents a man's name, and the numerical value of its letters is six hundred and sixty-six.)
(Revelations chapter 13: verses 16-18)"
Any reputable companies deploying RFID tags would be well advised to help get these evil RFID human implants banned, or risk being tarred with the same brush.
