cash is still faster though, you need to wait like 10 seconds to take them out of your pockets, and small shops need to wait for confirmations they can't accept pending deposit
Bitcoin will be as fast as cash. What time does it take to get a QR code scanned? because thats basically it to pay with a smartphone.
the problem are the confirmations not how fast is the transaction itself, because we know that this is instantaneous, so yeah you scan the qr, transaction go in less than a sec then you need to wait 1 to 6 confirmations depends on the shop...not practical
unless everyone begin to accept uncofirmed transactions
but this is only a problem with real life shops, i believe bitcoin will have two mainstream phase, one online(where confirmation time does not matter that much) and the second "offline", and with this we may need an hard fork or something else to resolve this issue about slow conf...
