The card-sized electronic data storage device includes an integrated circuit structure having a storage element for storing instructions, programs and data. The integrated circuit structure also includes a programmed processor in communication with the storage element. A signal receiving structure receives electromagnetic signals from an activation module, using the antenna structure. The card-sized electronic data storage device displays the determined graphical indicia on the addressable display assembly. The graphical indicia can represent information relating to many possible objects, including, for example, a financial account, a points-based account, a monetary account, a membership, a promotion service, a travel-related service account, a charge account, a credit account, a debit account, a bonus account, or an identification card.
