The system receives registration of a user at a business entity, such as a hotel and receives identification of a payment account associated with the user. Then the system establishes a policy such that the payment account is used as a key to unlock a door at the business entity, such as a hotel room. The system receives data associated with the payment account by receiving a card swipe at the hotel room door using a card associated with the payment account or via a wireless communication at the door. The door is unlocked based on validation of the data provided at the door."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for door unlocking using a payment account","description":"Disclosed herein are systems, methods, and computer-readable storage media for door unlocking using a payment account.
