All Things Considered

Lorie Miller bends over her grandparents' grave in north Philadelphia. She holds a two-inch brass square she's going to attach next to the headstone's names and dates.

Printed onto that square is a QR code — that square digital bar code you can scan with a smartphone. Miller peels off the back of her square to expose the adhesive and pushes it into place. The headstone, which otherwise looks the same as many others around it, has just jumped into the modern age.

Robby Benson began his career at the age of 12, on the Broadway stage, and became a teen heartthrob in the '70s, starring in films such as Ode To Billy Joe, Ice Castles and One on One, which he co-wrote. He was also the voice behind the Beast in the 1991 Disney film, Beauty and the Beast.

The western Afghan city of Herat has become a thriving hub for the money exchange business, a consequence of geography and politics. Money-changers throng the currency market carrying thick stacks of Iranian currency, much of it brought in by the hundreds of thousands of Afghan workers who earn their living in Iran.

While the stacks of crisp 100,000 rial notes that money-changers bring to the market might look like a small fortune, the 10 million rials in each of these stacks is worth less than $400, because the Iranian currency recently lost more than half of its value.

In an attempt to put down the insurgency in Afghanistan, the international community has spent millions to try to reintegrate former Taliban fighters and other militants back into society.

So how well has it worked?

Critics like Kate Clark of the Afghanistan Analysts Network say many militants use these programs to gain access to arms and money, without necessarily changing their ways.
