The source for actionable policy ideas to spur innovation.

Government ID programs such as the Department of Defense’s Common Access Card and the Transportation Worker Identification Credential should move to an open architecture that allows electronic wallet applications to be housed on the card.

One key to driving innovation through procurement is to support open standards architectures. By adopting technologies that are interoperable with non-federal applications, federal procurement can help drive widespread adoption. An open architecture would allow these cards to house electronic wallet applications that would, for example, let employees load a contactless payment application issued by transit authorities so they would not have to have a separate SmarTrip card to ride the Washington, D.C. metro system (or those of other transit authorities). The functionality would be integrated into one single card, which could also support other functions, such as a debit card to pay for meals in government cafeterias or fees in parking garages.
