Australia's mail service has injected modern technology into the simple postage stamp.
It has created a "video stamp" to deliver a personal message that recipients can view on their mobile phone.
Australia Post said the Video Stamp was the world's first to allow users to send a 15-second personalised video along with their packages.
It will be distributed free of charge on some parcel services in the pre-Christmas period. Richard Umbers, executive general manager of parcel and express services, said: "Christmas is a time when people want to be with their loved ones, but more and more friends and family are scattered across the country and around the globe.
"Australia Post has always helped people connect. This year we are doing more than ever to eliminate the tyranny of distance. The Video Stamp lets you send a little piece of yourself with your gift this Christmas."
The stamp can be accessed through a smartphone. To use it, senders scan the stamp, attach it to their parcel and record a personalised greeting using their smartphone and the free Australia Post Video Stamp app within 12 hours of posting.
