Mobile banking means a bank on a truck

Bank manager Juergen  Schaller  never expected to end up getting a trucker's licence and driving 20,000 km per year.

But as brick-and-mortar branches vanish from the rolling Franconia region of northern Bavaria, the neatly dressed savings bank executive jumps behind the wheel four days a week to bring mobile services -- including cash machine and consultation room -- to tiny countryside villages.

The switch from desk to dashboard has enabled  Schaller  "to do something else while staying in touch with the customers", he said.

High-street banks are increasingly being forced to shutter branches, as more and more customers go online, rural populations shrink and low interest rates eat into profits.

As a result, banks such as the public-sector Sparkassen, where  Schaller  is a branch manager, are having to rethink their business models.

In  Schaller's Kronach-Kulmbach district alone, six branches sporting the red "S" logo of the widely popular savings banks group closed their doors last year.

A similar trend is seen across the country as a whole: nationwide, the number of physical bank branches has plunged by a quarter over the past 15 years to 35 per 100,000 people, according to a study by public investment bank KfW.

The European average is 37 per 100,000, with Spaniards the most spoiled for choice with 67.

Steffen Haberzettl, the sales director for the Kronach-Kulmbach Sparkasse, said it was primarily local businesses and older people who had not embraced online banking who were taking advantage of the mobile branch, which first set off on its rounds in 2015.

Haberzettl estimated that around 20 people visited the bank at each stop, equivalent to 12,000 customer contacts a year -- a tiny number compared with some 8,800 online banking logins per day.

But "we invested in this service for our clients knowing that it wouldn't make enough money to pay for itself", he said.

In the bank's trailer, 70-something Maria Neubauer is happy to wait for an appointment with  Schaller  in his tiny office during his 90-minute stop opposite the church in the slate-tiled village of Tschirn.

"The Sparkasse bus is great for making transfers, or doing anything you need," she said.  "We're happy, especially those of us who don't have a car" to visit a branch further away, another villager Maria Greiner said as she printed an account statement from a nearby machine.

Other customers were busy withdrawing cash from the ATM embedded in the flank of the trailer. Schaller  makes his rounds to small villages such as this from Monday to Thursday, keeping Fridays free to do maintenance work on the red and white truck and trailer.
