For some time, I have followed the research of Professor Ian Kerr, the Canada Research Chair in Ethics, Law and Technology. He provides some critical insights into the field of implantables. Here is one such overview article written by Tim Lougheed in 2006 for University of Ottawa on the work of Ian Kerr.
"Life on the beach is pretty good already; but it gets even better when you no longer have to worry about carrying a wallet or ID to get a drink from the local watering hole. One enterprising bar owner in Spain has made this dream come true for his most exclusive patrons, who can show up with nothing more than their swim suits and buy as much as they want.
What distinguishes each of these customers is a tiny microchip inserted into their triceps, similar to those that are commonly implanted in cats and dogs. A simple scanner allows the device to identify members of the bar’s clientele, as well as clearing their purchases – all without having to enter so much as a PIN code.
For some, this prospect might seem like a slippery science-fiction slope of the most worrying kind: first a chip in the arm with free drinks, then a mandatory chipping policy for migrant workers, and, ultimately, the mindless, drone-like existence portrayed in Star Trek lore as the fate of the technologically rapacious Borg.
However, the regulars at Barcelona’s Baja Beach Club do not appear to be worried. And Faculty of Law professor Ian Kerr wants his students to witness this with their own eyes."
