GeldKarte

~ the obit ~

GeldKarte arrived in 1996 as an extra function on a card Germans already carried. The chip on the bank card could hold a balance of its own, loaded at an ATM or a dedicated charging machine, and then spent offline at a machine that had no way to phone a bank and ask. That offline part was the engineering argument. A vending machine in a stairwell or a parking meter on a side street had no data line in 1996, and both of them could read a chip and subtract from it.

The German banking industry ran it collectively rather than as a product from one bank, which is why it ended up on so many cards so fast. For a while the growth looked like the future of small payments in Europe. Usage peaked in 2007, both in the number of payments and the total value moved, and in 2009 about 132 million euros went through the system at an average of three euros a transaction.

Two things then happened to small payments. Card terminals got cheap and permanently connected, so the reason for an offline purse evaporated, and contactless arrived, so tapping a normal debit card for a three euro coffee became faster than remembering to top up a chip. The banks tried a refresh in 2012 with girogo, a contactless version of the same idea that found its niche in football stadiums and event venues. By 2018 fewer than one percent of the cards carrying GeldKarte functionality were being used for it.

The end was announced years ahead. Die Deutsche Kreditwirtschaft decided girocard would replace the prepaid functions, banks stopped issuing the chip purse on new cards, and the whole scheme was closed on 31 December 2024. Anyone with money still sitting on a chip had until the end of March 2025 to get it back from the issuing bank, and after that the only route was a conversation with the bank about a balance nothing could read anymore.

~ the cigarette machine clause ~

GeldKarte got a second life it was never designed for. From 1 January 2007 German cigarette vending machines were legally required to verify age, and the cheapest way to prove an adult was standing in front of a machine with no network connection was to make them insert a bank card. The chip could assert that its holder was over eighteen, offline, in a second.

That clause kept the format in circulation long after its payment business had stopped growing. A technology sustained by tobacco regulation is an unusual thing to find in a banking standard, and it is the part of the story most likely to outlive the scheme in people's memory.

~ the family plot ~

Europe built a generation of these chip purses in the nineties and every one of them is now dead. Mondex in the UK and Chipknip in the Netherlands were the same promise under different bank consortia, and Denmark's Danmønt got there before either. GeldKarte outlived all of them, by nineteen years in Danmønt's case and by nine in Chipknip's, because Germany kept paying cash for small amounts long after its neighbors stopped.

None of it ever left the country that issued it. A Turkish card could not hold a GeldKarte balance and a German one could not spend it abroad, which is exactly the flaw that made a single continent build the same product five times over instead of once.

~ the refund window ~

Three months is what the industry considered enough notice to collect your own money. The balances were tiny by definition, which means most of them were never claimed, and somewhere in the accounts of the German banking system there is a line for euros that were loaded onto a chip, forgotten, and switched off at the end of 2024.
