This document analyzes trends in U.S. government commercial card use from 2000-2013. It finds that while card use and associated savings rose significantly in the early 2000s due to efficiency gains, card use and spending has declined in recent years. This is possibly due to increased oversight and accountability measures dampening the programs. Military card use, in particular, has fallen further than civilian programs. The conclusion suggests that commercial cards can benefit government operations if the trade-off between efficiency and control is properly understood and communicated.
