A financial transaction card includes a first member, a second member, a side wall, at least one substantially rigid connection member, and an account identifier. The first member defines a first panel, and the second member defines a second panel. Each of the first panel and the second panel are substantially planar. The side wall extends between the first panel and the second panel such that the first panel is spaced from the second panel to define a void between the first panel and the second panel. The at least one substantially rigid connection member extends through the first member and interfaces with the second member to at least partially couple the first member to the second member. The account identifier associates the financial transaction card with an account or record having a value associated therewith. Other cards, assemblies and associated methods are also disclosed.
