SMS is set to replace the postage stamp in Sweden, as the Swedish postal service makes plans to launch a service that will enable consumers to text in for a unique code, which they then write on the letter as proof of payment of postage.
Anders Asberg from the Swedish postal service told the Swedish Sydsvenskan newspaper: "We are very interested and are just now looking into a solution."
The system will work for packages weighing up to 2kg and is likely to start in the summer. The Danish postal service plans to introduce a similar service in April.
Sweden is, of course, a very mobile-friendly nation. It is estimated that around half of the Swedish train service's tickets will be mobile by the end of the year.
