Another interesting development, after the e-book. It is amazing thought that this time it is done by a public company.
The internet has revolutionised the speed at which people communicate. Now the Swiss postal service is hoping to do the same for regular snail mail.
The company offers a service called Swiss Post Box to customers wanting to receive their physical letters over the internet.
This system was first developed by the Seattle-based company Earth Class Mail, which has its own subscribers around the world.
For 14 euros (£12) a month, letters are redirected to a secret location in Zurich where the envelopes are scanned and an image is e-mailed out to customers.
They can then decide whether letters should be opened and scanned by vetted personnel sworn to secrecy, or simply shredded.
