For online shop yes, and it does exist, but for real or offline store i doubt that we could see in the near future due to the confirmation time of bitcoin need to be improve, i usually buying some virtual things on internet but sometimes i have to be waiting to get 1 confirmation time untill my items was processing
Yes confirmation time will be great hurdle in spending bitcoin offline.Imagine waiting to leave a coffee shop after payment but you cant unless the shop owner see 1 confirmation would be a great embarrassment and waste of time as well
I'm not sure that's true (confirmation time being a great hurdle to BTC acceptance). I have seen and heard of cases (coffee purchases for example) where the recipient doesn't even bother waiting on a confirmation for small purchases.
Within the past year, for example, I do not have to sign (sometimes) for small credit card purchases.
I think the same principal applies here, for small purchases the risk is low of fraud, and the results not too painful for the merchant.
