Sticking a stamp to the front of an envelope could become so last century, if a logical plan in Europe ends up spreading as far as it could. Danish letter mailers, beginning April 1st, will be able to send an SMS to that nation's Postal Service and receive a short code back, confirming that they have paid to mail a letter.
