We are finally fast approaching a world with no keys, wallets, credit cards, security badges, parking meters, watches, remotes or dials of any kind. All we need is a charged and linked smart phone. All of the requisite technology already exists. It’s a matter of time before we can finally purchase and activate everything in our world. We can finally leave home with nothing but our phone.
And the tech exists so it’s not even a phone. It’s any voice activated and/or touch sensitive display on any worn material.
