If you hate waiting in line at a crowded bar for your next brew, Josh Goodman has got a solution for your.

Goodman, CEO of PourMyBeer -- a self-service beer system, is looking to revolutionize the way you drink.

"I was hanging out with my friends at a Baltimore sports bar before an Orioles game," the 36-year-old told CNNMoney. "We just couldn't get another beer served to us quickly."

Goodman launched PourMyBeer in Chicago in 2008 and, after a $20,000 injection of his own money, started partnering with a U.S. manufacturer to make beer tables with two or four service taps.

In 2009, a Baltimore tavern became the first bar to pick up his system and since then Goodman has grown his business to over 200 in 28 states and Canada.

Customers buy a radio-frequency identification--or RFID-enabled wristband or card to access the machine. Simply tap the access point, select a beer, and start tapping.  The units dispense only 32-ounces and no more than two beers at a time and the customer pays for exactly what they pour, kind of like pumping your own gas.

PourMyBeer is opening this week at Chicago's O’Hare Airport and expanding internationally to locations in Brazil and Italy later this year.

Table units start at $4,000 up to $16,000 for the “beer walls” which can display multiple taps. Goodman estimates that he’ll bring in $2 million in revenue by the end of 2015—his most profitable year to date.

One big benefit to Goodman’s beer system is the excitement it generates from bar goers eager to pour their own pints.

"People take pictures of themselves using it, and tag their friends," he said. "That's great advertising for us and it's also indirectly driving more traffic to the bars and restaurants."
