A credit card comprises a plastic layer, an integrated circuit (IC) holder for holding a removable electronic device (e.g., processor), and a means for providing power (e.g., a battery). The removable electronic device provides the ability to, at least temporarily, associate status, or promotional, information with the credit card for use in subsequent transactions. The status information is representative of, e.g., eligibility for a discount, preferred buyer status, etc.
