Abstract
Particular embodiments described herein provide for an electronic device that can be configured to couple to a terminal, verify an account with an account institution using Direct Anonymous Attestation (DAA), and request an action related to the account using DAA. In an example, the DAA is accomplished using enhanced privacy identification (EPID). The account institution can be a banking institution, and the requested action can be to add an electronic representation of monetary funds to the account. In another example, the device is a payment card, the terminal is a point of sale terminal, and the requested action is related to a sale of goods or services.
