Pick n' Leave

(The pick and leave concept)
The Shopping Chip

Connect a microscopic chip to wares in stores. Connect them to the entrance/exit to the store. When leaving the store the chip will be able to add all the wares you've chosen and added them together and by the help of your chip you will be able to buy the products without registering them. This allow for less people to work in a store. Things will go automatically. This will also make it way more efficiently to go shopping!

If you can't afford the chosen products you'll be warned by the exit detectors.

Re-usable microchips

The chip can be connected to the wares and be reused by attaching the chip to the wares, and removing them after.

[Theory] Start by adding a couple of identified prints of the microchip to the detectors. Then work on making the register under the signal. Six different variable will work out first. Then we can start dividing them into separate sub modes, with more identifiable microchips.

Make  a computer system. Python would probably be the right coding system. Learn how to use raspberry pi.

A guard could be there for security reason, depending on the history of the stolen objects.
