Well, we can actually implement some other optiins like putting up the funds in a card where we only need to tap it to pay amounts we need or else is to pay thr gasoline in a distant counter, as simple as qr scanning will do, becauss most of the time, we get tired especially if it is a public transportation and we're late, the driver needs to ciunt his money first for payment but with crypto, transactions will be faster.
