Music festival season is upon us, kicking off with one of the biggest and most popular festivals of them all — Coachella. If you’re headed to the festival in a few weeks, you won’t need to stand in any ATM lines. In fact, you may not even need to take out your wallet. That’s because this year, you can pay with your phone for everything. Square is the exclusive point of sale at the festival, and every vendor will be using the latest (and fastest) Square Reader.
