The PIN is accepted by a micro-controller that uses the entered PIN as an encryption key for decrypting stored account information. A portion of the account information includes data, that when decrypted, contains an image that is rendered on an integral display, with account information sent to a transaction terminal. A timer is used to limit access to account data while in the unlocked state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Security aspects of a self-authenticating credit card","description":"A self-authenticating credit card includes an input device for entering a PIN.
