net.wars: The cost of money

Everyone except James Allan scrabbled in the bag Joe DiVanna brought with him to the Digital Money Forum (my share: a well-rubbed 1908 copper penny). To be fair, Allan had already left by then. But even if he hadn't he'd have disdained the bag. I offered him my pocketful of medium-sized change and he looked as disgusted as if it were a handkerchief full of snot. That's what living without cash for two years will do to you.

Listen, buddy, like the great George Carlin said, your immune system needs practice.

People in developed countries talk a good game about doing away with cash in favour of credit cards, debit cards, and Oyster cards, but the reality, as Michael Salmony pointed out, is that 80 percent of payments in Europe are… cash. Cash seems free to consumers (where cards have clearer charges), but it costs European banks €84 billion a year. Less visibly banks also benefit (when the shadow economy hoards high-value notes it's an interest-free loan), and governments profit from Seigniorage (when people buy but do not spend coins).

"Any survey about payment methods," Salmony said Wednesday, "reveals that in all categories cash is the preferred payment method." You can buy a carrot or a car; it costs you nothing directly; it's anonymous, fast, and efficient. "If you talk directly to supermarkets, they all agree that cash is brilliant – they have sorting machines, counting machines… It's optimized so well, much better than cards."

The "unbanked", of course, such as the London migrants Kavita Datta studies, have no other options. Talk about the digital divide, this is the digital money divide: the cashless society excludes people who can't show passports, can't prove their address, or are too poor to have anything to bank with.

"You can get a job without a visa, but not without a bank account," one migrant worker told her. Electronic payments, ain't they grand?

But go to Africa, Asia, or South America, and everything turns upside down. There, too, cash is king – but there, unlike here with banks and ATMs on every corner and a fully functioning system of credit cards and other substitutes, cash is a terrible burden. Of the 2.6 billion people living on less than $2 a day, said Ignacio Mas, fewer than 10 percent have access to formal financial services. Poor people do save, he said, but their lack of good options means they save in bad ways.

They may not have banks, but most do have mobile phones, and therefore digital money means no long multi-bus rides to pay bills.

It means being able to send money home at low cost. It means saving money that can't be easily stolen. In Ghana 80 percent of the population have no access to financial services – but 80 percent are covered by MTN, which is partnering with the banks to fill the gap. In Pakistan, Tameer Microfinance Bank partnered with Telenor to launch Easy-Peisa, which did 150,000 transactions its first month and expects a million by December. One million people produce milk in Pakistan; Nestle pays them all painfully by cheque every month. The opportunity in these countries to leapfrog traditional banking and head into digital payments is staggering, and our banks won't even care. The average account balance of customers for Kenya's M-Pesa customers is…$3.

When we're not destroying our financial system, we have more choices. If we're going to replace cash, what do we replace it with and what do we need? Really smart people to figure out how to do it right – like Isaac Newton, said Thomas Levenson. (Really. Who knew Isaac Newton had a whole other life chasing counterfeiters?) Law and partnership protocols and banks to become service providers for peer-to-peer finance, said Chris Cook. "An iTunes moment," said Andrew Curry. The democratization of money, suggested conference organizer David Birch

"If money is electronic and cashless, what difference does it make what currency we use?" Why not…kilowatt hours? You're always going to need to heat your house. Global warming doesn't mean never having to say you're cold.

Personally, I always thought that if our society completely collapsed, it would be an excellent idea to have a stash of cigarettes, chocolate, booze, and toilet paper. But these guys seemed more interested in the notion of Facebook units. Well, why not? A currency can be anything. Second Life has Linden dollars, and people sell virtual game world gold for real money on eBay.

I'd say for the same reason that most people still walk around with notes in their wallet and coins in their pocket: we need to take our increasing abstraction step by step. Many have failed with digital cash, despite excellent technology, because they asked people to put "real" money into strange units with no social meaning and no stored trust. Birch is right: storing value in an Oyster card is no different than storing value in Beenz. But if you say that money is now so abstract that it's a collective hallucination, then the corroborative details that give artistic verisimilitude to an otherwise bald and unconvincing currency really matter.
