A payment takes 10 min to process. In what store can you buy something under 10 minute really?

Sometimes you have to wait 15 min at the tilt because the employee is a moron, if you could do that in 10 min i`d be very happy.

You just buy the stuff quick, pay for it, then put the bought stuff in a safe storage inside the magazine, and go looking at the other products until you wait for verification. Then after the verification is done, pickup your bought goods and leave.

It would change shopping habits, but whatever.

No ,that would make people leave..Really once blockchain see's the transaction you are good .i have stood their and tried to double spend and never succeeded(Testing) So , if you really want bitcoin to be used by the masses . Maybe try going to a real store and spending some ?

Not all blocks take 10 minutes, that's the average time but some of them I have seen to take more than an hour. It is a minor problem and it has been discussed before but if any store does starts to accept BTC as a payment method then the person paying with bitcoin has to wait until the Tx has received 1 confirmation because the shop owner won't accept payment until it has 1 confirmation and for now this is how it is.

Ok plan B

Have an offchain bitcoin based payment processor designed solely for shop purchases.

You sign up to this payment processor, deposit like 2 bitcoins, and then go on shopping. When you pay for the goods & services you pay directly from the PP's account you hold with them, which would take 15 sec perhaps like if you would buy with credit/debit cards

This would be an easy off-chain solution, and would need a bit of technical integration from the vendor's part.

But i`m sure something like XAPO or similar could come up with an offchain system like this.

plan c

The shop itself should have an internal account with you. Most shops already give out fidelity cards, perhaps they can give out debit cards now and you can have an accoutn with them.

Especially big hypermarkets and plaza's so you just make an account there deposit 2-3 bitcoins when you enter, buy it off and then you leave you can take out the change.

Plan B: Offchain wallets are generally aren't safe. You would have to trust the operator to store your coins in the safest way. There is a risk of the operator running away. One of the biggest scam is inputs.io. They appeared to be quite trusted to majority of the Bitcoin community. In the end, they got "hacked" and 4100BTC were lost. Also, the shop owner must be sure that the operator will not block off their payment and there is no way to prove that the user had actual coins and coins weren't created out of the thin air.
Plan C: This would be like a debit and credit card. This again, requires trust. It is a hassle to maintain so many cards and it would cost some money to issue the cards. This would also cause the centralisation of coins.

As others have said, accepting 0 conf transactions is secure enough. There are less risk associated with it now if precautions are taken.
