A validation terminal located at a registered location comprises a barcode reader, a memory, and a processor. The memory stores a public key that is paired with a private key linked with the registered location of the validation terminal. The processor is operably coupled to the barcode reader and the memory, and is configured to detect an encrypted barcode that was scanned by the barcode reader from a mobile device that is located at the registered location of the validation terminal. The encrypted barcode is based at least in part upon transaction information associated with products in a digital cart, and the encrypted barcode is encrypted using the private key. The processor is further configured to decrypt the encrypted barcode using the stored public key, and to indicate the transaction is valid in response to decrypting the encrypted barcode using the public key.

Validation using key pairs and interprocess communications

A system includes a server and merchant device. The server receives product information for a product scanned by a mobile device. The server stores the product information for the product in a digital cart. The server receives a transaction request from the mobile device, determines that the product is associated with a validation requirement, and transmits a validation request to the merchant device. The server receives, from the merchant device, an indication that the validation requirement is satisfied, processes a transaction, and transmits, to the merchant device, an indication that the transaction is complete. The merchant device receives the validation request, determines that the validation requirement is satisfied, and transmits the indication that the validation requirement is satisfied to the server. The merchant device receives, from the server, the indication that the transaction is complete and displays the indication that the transaction on the display.

Digital cart monitoring and validation using interprocess communication

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.
