Imagine not having to carry your wallet. I'm not talking about not carrying the cash. I'm talking about not carrying the wallet at all.
Everything we have in our wallet can be replaced with a cellphone except for one little detail - banks. The credit card companies don’t want us to replace the plastic. The reason for this is if we were allowed to pay with our cellphones then the transfer fees could also go to the telecom companies instead of to just the credit card company.
But let’s not raise that now and allow ourselves to imagine a wallet free world.
