Music festivals are putting a wallet on your wrist.
All you do is tap you're wrist band on the portal, and wallah, you have whatever you need within 10 seconds.
In Outside Land in San Fransisco, festival goers are given wrist bands that use radio frequency identification technology.
It doesn't require cellphone service or internet connection to work.
It doesn't need wi-fi.
It doesn't need anything else.
It connects directly to the terminals that are there to make them digital wallets.
The wristbands act as an entry pass to the festival.
But also let visitors pay for food, drinks and merchandise.
Uses pre-load money on the band with cash, credit card or PayPal.
So now I've loaded up my wrist band with some money let's go see if it works and buy some waffle fries.
Could I please have the Philly.
And now we wait.
There you go.
Similar RFID technology has been deployed at other music festivals like Lollapalooza and Austin City Limits.
Even if you didn't use up all your money on the $15 price, refunds of the remaining balance are available.
