A case for holding a contactless smart card includes a set of plastic walls for defining a generally planar space. The space may be for housing one smart card or alternatively may be for housing two smart cards. The walls include two parallel walls which each have a planar extent that corresponds to a planar extent of the generally planar space. The two parallel walls include a first wall and a second wall. The first wall has an actuation region formed therein to permit a user's finger to actuate, through the first wall, a switch on the smart card. If the case is for holding two cards, then there is also an actuation region in the second wall. In some embodiments, the case may include additional spaces each for housing one or two cards.
