A method is disclosed for embedding an image during a transaction at a point-of-sale system. The method may include obtaining a first digital image coded to display a call to action and a placeholder occupying a specific position with respect to the call to action. A computer system associated with the point-of-sale system may interpret the first digital image to collect data identifying the specific position of the placeholder. The computer system may obtain a two-dimensional barcode encoded with a transaction identification unique to the transaction. Using the collected data, the computer system may generate a third digital image coded to display the call to action and the two-dimensional barcode. The two-dimensional barcode may occupy the specific position with respect to the call to action. The point-of-sale system may display the third digital image to a customer associated with the transaction via a receipt, a customer-facing screen, or the like.
