These digital stamps can also contain tracking information so that companies can retrieve information on a parcels' whereabouts at any given time. All these costs can be recorded and linked to the address, allowing companies to monitor their postage expenditure, which address mail is being sent out to most frequently, and whether amalgamation of mail can be done when different departments in the same company need to send information to the same address. If there is an international digital stamp standard, it will eventually be possible for mail to be sorted by machines almost entirely through the delivery process. The only human contact being that of collecting mail from the post box and delivery to the recipient's letterbox. This cuts down on error and theft.
Mail is delivered more efficiently and safely.
But the advantages of the digital stamp aren't just for companies to enjoy. Every digital stamp should be completely customizable, allowing stamps to be printed in any shape and colour. The only standard format required is that of a readable bar code containing the local postal code or country code or any other necessary information, printed above every picture. Part of the joy of using conventional mail instead of electronic mail is the pleasure of sending and receiving letters. Even though non-electronic mail is slower, it can be more personable.
