What’s on tap? Ad agency gives free beer for time cards

Let’s face it, no one enjoys filling out timesheets — yet they are imperative in order to get paid. That’s why Minneapolis ad agency Colle + McVoy has devised a new way to not only get employees to fill out their time cards, but to reward them with some draft beer.


Dubbed TapServer, the multi-keg beer deployment system combines RFID tags and some custom-written software to seamlessly sync with the agency’s time-keeping application. On the hardware side, the program is comprised of several Arduino Uno boards (ATmega328), a Node-based server, solenoids and a Raspberry Pi.

How does it work? It’s rather simple. Employees are given RFID-enabled key cards, which they scan at the TapServer. This instantly verifies whether their timesheets are up-to-date. If their records are indeed complete, employees use the connected iPad to select their beer, then pull their pint.

As an added feature, TapServer can also keep track of ounces consumed per employee and beer brand.

Full sheet = Full glass. We’ll cheers to that!
