Amazon Go

Not many comments about privacy. This is how I see it: You are identified when you enter the shop and amazon knows exactly the products you buy.

If you have the choice to buy or not to buy at the shop, that's fine, it is your decision. But let's imagine that in the not so far future, all shops in your neighborhood are like this. No way to go shopping whithout given exact trace of you, your location, the stuff you buy, the time you buy, the amount of food etc.

We all know that too much data is not good for us (yes, I am looking at you, my government).

While I like the idea of not standing in a line and wait, I really wish that these shops offer a prepaid anonymous card for those who don't want to be totally tracked.

I think the privacy implications for a shopper at Amazon Go are the same as a shopper who shops at Tesco with a credit card. The company can use your credit card to track exactly what you buy already and many people seem to be happy with that (even going so far as to sign up for loyalty cards).

But it should be possible to a) use a prepaid credit card or b) pay with good old cash. That way it is still possible to buy without getting tracked (while all the others that don't care use the loyalty card).
