Abstract: A secure method for submitting purchase orders wherein a QR scanner and email platform such as in an iPhone™ (14) prepares an email message for the purchase of goods or services from the scan of a two-dimensional bar code (10). The email is transmitted to computer (22) of a provider for the goods or services through servers (24 and 26) that cooperate through Internet cloud (28). Computer (22) compares source data in the email message against pre-determined source data stored in computer (22) and an acknowledgement email is returned to iPhone (14) if there is a positive comparison. In some cases, the provider is not authorized to complete the order until the source receives the acknowledgement at iPhone (14) and returns a confirmation to computer (22).
