Some canadian coins have been found with tiny radio transmitters: http://www.cbc.ca/technology/story/2007/01/10/rfid-defence.html
It's not entirely out of the realm of possibilities, but why do I think that most of these wound up at a Tim Hortons... or maybe a Harveys, or a Second Cup...
I wonder how it is possible to fit an RFID tag to a coin,as you would be able to see it.I don't know what the reputation of the Canadian Security & Intelligence Service (C.S.I.S.) is like,but the F.B.I. & the C.I.A. are feared,as is the Russian F.S.B. (successor to the K.G.B.). Aidan.

Better be careful! Big Brother is tracking this, and doesn't like it when you fabricate facts about his coins (they were really MS-74's).:goofer:
After 6 years with a security clearance and constant drilling buy US guys in suits, I am as paranoid as they come. I worked in the security industry for more than 13 years. I was part of a private group that worked on early RFID cards and readers. The RFID IC chip that goes into the badge on the attached photo is a little bigger than a pinhead and the antenna can be very small and thin. (Very easy to conceal) The bigger question is how to transmit with the metal from the coin around it. Normally the metal from the coin would detune the antenna connected to the chip. They may use the coin metal as a form of antenna? The range for this type of chip is even with the coin as an antenna would be very short and would have to be powered from a RF reader in close proximity. (this is how it is done even for larger animal tags) It is more likely that it is some form of RF transmitter with a small battery(probably a short life though). Again they would probably have to use the coin as the antenna to get enough strength. This would be an active signal and could transmit potentially far enough not to be noticed by someone unsuspecting (maybe 100', maybe more?). If the coin was handed off, the bad guys could get the coin back by asking for specific change and offering a bonus - for say any large coins like a half or silver dollars. I'll do it if I see one sitting in a cash drawer. Hope this helps explain how it might be done. Darryl
It just doesn't make sense to me. Say the guy who the coin is passed off to, goes straight to a gas station, fills up on gas, buys a soda and a bag of chips, and uses the coin in the purchase. Minutes later, someone else could get the coin in change from their purchase. Before long the coin could be many miles away from the person its supposed to be tracking? I don't know, so pretty stupid to me.
How about a plausable theory LOL some one is doing a study on the movement of coins for example how far one can travel in a given period of time De Orc Ps not as silly as it sounds one of the Major universities over here once did a servay on how many and what type of teligraph poles there were in Yorkshire :rolling:
People on business trips tend to go from one site visit to another to maximize efficiency. Also if the transmitter was a real listening device the bad guys might get insight into information the contractors would not share with outside individuals. This could include state secrets, competitive information, on and on. FYI - Tom Clancy picked up a lot of classified information for "Hunt for Red October" by working in a diner in New London - Near the US Sub Base and Electric Boat who builds the subs. People would come in and talk about things they shouldn't have been in public even if they thought no one was listening. Probably why the guys in suits spend so much time preaching about keeping our mouths shut. For example - If you were with a friend at a coin show, after visiting a booth you might walk away and share your honest thoughts with your friend that you would not have said to the dealer.?. There is MUCH to gain from inside information.
The Chinese make most of our clothing ( some others also ). Think of the reception you could get from a uniform shirt that has a semimetalic thread embedded in the clothing. You would look like times square on New years on Radar.
Problem with cloathing (unless it is a jacket) is that it would probably send the metal detectors nuts at an airport. It would have to be real close to the zipper in the pants. (now thats scary) A guard using a wand would not pay much attention to this area if the signal was weak enough. Big coins - you would put in the basket to go around the detectors. Jackets have their own issues as the thread/chip may show up on the scanners you send everything else through.?. You could conseal in metal buttons if you are lucky to have a jacket with metal buttons on a target. Coins are a good transport as no one generally pays attention to them. Now get someones cell phone or laptop and then you are in business. You could piggyback off their power and the device would always be near the subject.
Possibly a dumb thing to even try. It would be just to simple to put transmitters in things like the new keys used for your car. They could be put in the frames of your glasses, heels of your shoes, in pens, brief cases, car seats, garbage can lids and even inside a roll of toilet paper. Now how would you like that. A foreign government could then find out how many times you went to the washroom. If in a coin someone would give it to their kid, take it to school or throw it in a wishing well.
I grew up in the 1980s in Anne Arundel Co., Maryland, home to the "No Such Agency" (NSA). They had a big to-do banning Furbies because the voice recorder in the Furbie might be used to record state secrets.
Common knowledge If you go to a job Fair at one of the Schools such as Monterey Institute of Internation Studies you will get to talk to some of the agencies. NSA requires you have a vehicle transmitter on your personal vehicle and that all your phone calls are recorded. One of my children looked at that and turned to the more lucative private sector and SHE is doing very well indeed.The school is located near the Naval language school and U.S. Army School of Languages. The rest of this above is fun to do to see how people react. Yea there are alot of concerned Americans out there.
