A scannable matrix barcode image can be configured to initiate the composition of an electronic mail message. Upon scanning, the user’s device automatically populates the email client with a pre-defined recipient address, subject line, and potentially a body text, streamlining the process of sending correspondence. For example, a poster advertising an event could feature such a code; scanning it would open an email pre-addressed to the event organizer with a subject like “RSVP” and a blank body for the user’s message.
This application provides a convenient method for users to quickly engage with organizations or individuals, bypassing the need to manually enter contact information.
