Bitcoin transactions are normal but the time taken for confirmation message of that transaction is more. It has to be solved otherwise buying goods in shops using bitcoins would remain only as a dream.
I dont see why you saying make any shop with bitcoin will remain a dream, you know you can get a debit card use your bitcoin balance to make the payments, i dont know where those card will be accepted, but i do remember to someone went into market and pay with his card of bitcoin. I do understand you do wanna to pay directly with your phone, get the code and transfer the bitcoins, but those will require extra time, and at the moment the confirmations might be an issue since the money can be double spent.
