We use something similar at our company, we use the http://www.achievers.com/ http://www.achievers.com/ platform for this. We get new credit every month, which we can give to anyone in that month, but if you do not give them away they expire. We do not talk about big bonuses (as I am aware the credits value is different by location, at mine it is much less then 100 USD for a month), but yeah, it is abused.. Some colleagues just exchange it on the end of the month.
