Read up on piggly wiggly. It was among the first to have shopping carts and people could roam through the store to buy stuff. The old model was to present a list to a shop keeper and they would get your items and hand them to you after payment. The old model didn't lend itself to branding since a generic scoop of cornflakes looks the same regardless of brands. The piggly wiggly owner realized that impulse buys, premium brands, and saving in shop keeper time more than made up for the slight theft caused by allowing people to pick their own food.

In the end, the (((bankers))) stole his business. They tried to crash his stock and he realized it. Then they changed the rules of the stock exchange to make sure he couldn't win. Another innovation captured and destroyed by parasites. Ironically, the old model will probably return (behind bullet proof glass) for all the inner cities. Mafia protection rackets are already returning, but unfortunately they are democrat affiliated mexican cartels.

Be me getting paid to install and fix anti theft systems in stores. lolololololol

This all leads to biometrics being used to access retail stores. Basically, you will need an iris scan or fingerprint scan in order to open the doors to enter Target and other places. This will happen in the future.
