Paradoxes in the notion of mobile billing replacing cash or credit cards

I continue to read supposedly-visionary pieces proclaiming the imminent death of either cash or credit cards, proclaiming that mobile operators will run the banks into the ground. As this wise sage points out, "Banks and credit card companies of the world, be very afraid. The operators will come to take your business away".

Apparently, we'll all be waving NFC-enabled phones at retailers' readers or transport systems' ticket barriers, and can kiss good-bye to the mess of credit and store cards lurking in our wallets.

In fact, we can forget about wallets too - the leather industry is destined for an implosion of catastrophic proportions. The coin industry is, similarly, quaking in its boots, seemingly scared of the "truth" as peddled by the all-knowing T Ahonen and others.

We have, of course, all the reference sites we need, with Safaricom's impressive M-Pesa mobile money platform, and NTT DoCoMo's Felica NFC-style functionality. And of course, the rumours suggest that the iPhone 5 will be NFC-enabled.

So this must all be true.

But just for the sake of argument, and being disruptive, let's have a look at some contrarian observations:

• 70%+ of the world's mobile subscribers, and essentially all those who are "unbanked", rely on prepay. The most typical way to top up prepay accounts is with scratch-cards or vouchers. Which are usually paid for with cash.
• There's also quite a lot of prepay credit that's bought with the help of bank cards, at an ATM machine. Probably more, in fact, than we're seeing bank card payments substituted by phone payments.
• The average mobile prepaid credit balance is something like $5 (much lower in developing countries) and is frequently zero. Not idea for doing your shopping, or even buying a coffee.
• Even some of the most enthusiastic NFC-promoting operators don't believe in the idea that customers will charge purchases to their phone bill or prepay accounts. They're providing hooks so that they can funnel payments to the user's choice of credit-card account, Paypal or another source of funds. Few customers want a fridge or airfare appearing on their bills at the end of the month. I had a recent conversation with a senior exec in one of the most NFC-friendly operators, and his view is that the bill is fine for small digital goods, but not major purchases
• Governments rather like cash and seem unlikely to want to permit or encourage its death. It's a bit difficult to do quantitative easing via mobile phone.
• In the SafariCom example, M-Pesa accounts are distinct from the mobile phone airtime account. It's basically a bank with a mobile-phone front end. Which makes a lot of sense, especially for the "unbanked" who would otherwise have cash stuffed under the bed & would be unable to make payments. But it's not the mainstream view of a "mobile wallet" substituting for cards or cash in developed economies.
• There are no "payment portability" or "mobile banking portability" laws yet. Given that most (all?) operator mobile payments linked to an access account, users unlikely to lock themselves in & embrace huge switching costs when they want to churn phone provider. Obviously operators want to reduce churn, but assuming your customers are gullible and stupid is not a longterm winning strategy. Loyalty isn't the same as lock-in.
• DoCoMo has spent rather a lot of money to get its payment solution accepted - including a near-$1bn investment in Sumitomo Mitsui Card in 2005 and the purchase of a stake in Lawson's convenience store chain. I don't see many other telcos stepping up to the plate with that sort of cash or serious intent.
• Central banking stats generally show "currency in circulation" continuing to rise, despite the presence of many alternative large and successful payment mechanisms such as debit cards. The chances that mobile payments will make a dent? Almost zero.

Taken as a whole, my view is that mobile payments have a very important role to play in markets like Kenya, where there are significant numbers "unbanked", big problems in distributing money such as salaries (eg Afghanistan) or Japan where a combination of culture (eg trusting the telcos) and heavy investment by the likes of DoCoMo can make a big impact.

I can also see some payments being facilitated by mobile phones (and in some cases operators) and being directed to existing channels such as cards, bank accounts, Paypal or iTunes.

But this clamour that "cash is dead", "the wallet is dead" or "credit cards are toast" is complete nonsense, now and for the forseeable future. I'd be more willing to believe that retina-scans, DNA authentication, telepathy or a William Gibson style direct neural interface for payments will happen first.
