Abstract
A validation system that includes a server and a validation terminal. The server is configured to receive location information for a mobile device and to determine the mobile device is at a registered location. The server is further configured to process a transaction for the products in a digital cart, to generate a barcode, and to encrypt the barcode using a private key linked with the registered location. The server is further configured to send the encrypted barcode to the mobile device. The validation engine is configured to scan the encrypted barcode using a barcode reader and to decrypt the encrypted barcode using the stored public key that is linked with the private key. The validation terminal is further configured to indicate the transaction is valid in response to decrypting the encrypted barcode using the public key.
