This could be adapted for use as ID, can be scanned by paramedics or hospital/Doctor surgery staff, and have instant contact details, name, medical problems etc etc in case of accident or medical collapse.
There are a lot of ways to get good customer service in a club. You could tip heavily. You could become a regular and ingratiate yourself with the staff. You could get your friends or roommates jobs as bartenders and then mooch off them all night.
Or, if you're feeling particularly bold, you could get a RFID chip implanted in your arm, giving you VIP status, a debit account for your drinks and just a little bit of 1984-style sci-fi paranoia.
RFID is a term you'll be hearing a lot about in the near future. It stands for Radio Frequency Identification, and it's basically new type of chip that is already being used in consumer products around the world. It will soon replace UPC codes and anti-theft devices in retail stores. Even better (or worse), it can track where products go, and who uses them -– raising the hackles of privacy advocates everywhere (think of the targeted advertising in films like Minority Report).
Instead of sticking a RDID tag in a pair of shoes or a DVD, one nightclub is using them to tag people. The Baja Beach Club in Barcelona, Spain is the first venue in the world to offer tagging to its VIP customers.
Why would you want even your favorite club to implant a tracking device in your arm? Users can be tagged as VIPs, giving staff immediate information on what their favorite drinks are, if they're worthy of entering the VIP section and even act as a debit account for drinks, negating the need to carry any actual cash around with you.
Conrad Chase, the American owner of the Baja Beach Club told Sync magazine, "This technology will work on a global level; it will destroy the need to carry ID documents and credit cards."
A BBC producer went through the procedure. He described the actual injection, saying, "[the nurse] held up the rather large needle containing the microchip and inserted it beneath the layer of skin and fat on my arm. She pressed the injector and it was in."
If you want to opt out of the system, the chip can be surgically removed at any point.
While the chip has not yet been approved for use in the U.S., RFID technology is making major inroads. One of the big growth areas is a similar kind of chip implant for pets -– enabling lost animals to be identified and returned to their owners. And it's only a small step from tagging your miniature poodle to signing up for a permanent tab at your favorite high-end hotspot.
