There is something personal about a postcard that beats the privacy of finger print-protected smartphones. Beyond the message, it carries a glimpse of its sender's personality — the slant of letters, the choice of ink, the pressure on the pen, even the state of mind when the postcard was written. But that's a thing of the past, and attempts at reviving the use of postcards have enjoyed only limited success.
