Getting a parking ticket sucks, but paying for it shouldn’t have to be. That’s what the folks at Boston’s Terrible Labs think anyway — they built an app called TicketZen to take the trouble out of giving the state your money. Here’s the gist of it: once you’ve installed the iOS or Android app, you can use it to scan a barcode on your parking ticket to import all the pertinent data and pay it off with a touch. Don’t see a barcode? That’s fine, too. Not every town is that forward-thinking, so you can punch in the violation number instead.
