Is it true that RFID chips can be defeated with aluminum Foil?

Yes they can be. And I assume your question was focused on RFID tags (rather than chips), used to prevent going out a retail store with an unpaid product. The aluminum foil will reflect the RF signal, so they can't  get a read at all. I think they have methods know to prevent that from happening. So I wouldn't recommend trying this in real life, you would be arrested.

No way.  Once that microchip is inserted, you'll have absolutely no privacy for the rest of your life.

I would look into the system used by EZpass on highways and certain medications.RFID tags. They are usually from two to four square inches in size, and contain a silicon chip that holds a unique string of numbers identifying the item to which it is attached. A separate RFID "reader" receives the information contained in the tag through the tag's antenna. Unlike a bar code, the signal does not have to be read directly by a scanner; RFID signals need only to be in the vicinity of an RFID reader.

Many GPS units not only receive, but also transmit.  Devices that transmit radio frequencies are not allowed on airplanes per FAA regulations because the transmissions could cause problems for the control panels in the planes.\n\nNow, before you go thinking you're able to take down a 500 million dollar piece of machinery with that little toy you just bought from Radio Shack ... NO.  Almost all modern airplanes have their wiring shielded, so this isn't an issue.  But the FAA would have to test every electronic device with every single type of aircraft to make sure, because we don't want that 1 in a million chance to occur again (research cell phones on airplanes).

You can do what they do for airliners to protect them for radio interference.  Since an EMP is just a very concentrated radio wave this should work.  Take some tin mesh and wrap it around the electronic device you wish to protect.  This will create a great barrier because it causes the radio wave to be absorbed by it, with no damage to the electronics inside it.

Nanotech is indeed real. Have you never seen surveillance cameras the size of a dime, and what about tracking devices about the size of a cigarette lighter?Do you remember how many different components use to be in a regular am radio & tv set? Tubes, capacitors, resistors, coils, etc. are now on a pc circuit board in the form of an integrated circuit about 1"x1/4". The first computer ever devised needed many rooms to house. The laptop now is less than the sise of some wire bound notebooks high school kids carry.

Yes. And for good cause.\n\n(Psst. They are against you, too. They told me.)\n\n(Well, they didn't so much "tell" me as they did beam it into my head via microwaves...but still.)\n\n(Are you done with that roll of aluminum foil?)

The side that you're referring to as the recording side is actually a protecive layer. Under that layer you will find a thin foil. The thin foil is acuatlly what retains the data in the format of pits and grooves. \nMore info at: \nhttp://electronics.howstuffworks.com/cd.htm

sure, not all parts are necessarly bench tested before packaging. you could have had a pin that did not fully insert or the insertion of the actual chip into its metal clad package did not fully seat itself.  It could have been dropped, crushed, or heated to hot in a truck.  depending on where you bought it from, you could even of been sold a fake chip.

nanotechnology is working with microchips and tiny electrical stuff.

I have a microchip implanted in my left arm just above my elbow. It can be traced by using GPS, supermarket checkout scanners and garage door openers.

Actually I have tried this, It is very difficult to erase a credit card with incidental contact with magnets. Audio video and floppies, Just think about it and they are gone!

Radio Frequency Identification (RFID) cards contain tiny transceivers which are activated when the pass near a sensor.\n\nSome are self-powered (active), with a tiny built-in battery but most are "passive" cards, powered by an induced current from the sensor unit. Active cards have a much greater range and must be used whenever distance from the sensor is a factor. This generally is not an issue for proximity card applications.\n\nRFID chips can be read-only -- a simple fixed code is transmitted which identifies the card or product -- or read-write, where information contained on the card or tag can be modified.

The chips are usually soldered in place on a printed circuit board, and the odds that you could desolder them without grounding or shorting any pins are small indeed. That makes the answer to this question almost positively no, the data will not remain.

The majority of passive tags use EEPROM memory. Some are laser programmed at the silicon level. Many active tags utilize battery-backed SRAM.
