Today, I made my first ever contactless payment with my first contactless card! I held the card about an inch away from the terminal and the shop clerk told me that it is better if I touch the terminal with the card. (so much for CONTACTLESS) And knowing that certain pieces of human garbage around the world spend their sad and meaningless existence going around with a receiver, collecting people's card data, and given that this can be done from quite a distance, it surprised me that I had to get closer to the terminal than an inch away. Although I'm sure that you would say that they are using significantly higher powered receivers than a point of sale terminal. Although, given that most people will keep their cards in a wallet or purse, it does seem quite impossible.That would depend on many, many things. From orientation....to hardware and software.
If it did.....it probably wouldn't last long.
There is new tech coming for powering all this kind of stuff. It's because of the low current/power requirements for the new chip circuitry. In almost any environment now(even in a pocket)....energy will be harvested for wireless connectivity.
Sorry, what is the "it" in all of that?With the size, function, memory, and power.....and being able to stamp this stuff out cheaply....It is being used for a lot of product tracking now. It just doesn't track...it can log the environment.(even acceleration) A complete time line history since manufacture. 100% quality control.
