People pull out their signing device to complete the transaction

So far they've only showed "the bad people" using it.

Bitcoin talk without any mention of Silk Road or illegal activity in a movie? Impossible 😂

It’s going to look like Hackers or Johnny Mnemonic with 3D bitcoins flying around cyber space. Maybe some cyber hornets with Michael Saylor’s face or something too.

I would think it would be a simple NFC transaction. With an emphasis on the amount sent.

There would be that anxious waiting to get confirmation on the block, all the while henchmen on both sides have itchy trigger fingers.
