London's Tube Is Getting 'Contactless' Payments. Could They Work in the U.S.?

Could public transportation help new payment technologies enter the mainstream?

London's transit agency, Transport for London, announced the rollout of contactless credit card readers on all of the city's 8,500 buses last month, allowing riders to charge their bus fare directly to their bank accounts. Previously, Londoners had the option of paying a discounted fare with a prepaid Oyster card or handing over an extra pound and paying in cash.  Now, anyone with one of Britain's 30 million contactless credit cards can avoid being one of the daily 36,000 people who "[dash] to board a bus only to discover that [their] Oyster card has run out of credit" and then have to "scrabble for change" and pay a higher fare, as London's Mayor Boris Johnson press release explained. Transportation for London expects that Londoners will be able to use this technology on the underground Tube and aboveground trams by the end of 2013.

In theory, this is exciting news for London commuters who loathe change-scrabbling, but even more so for credit card companies, who will now ostensibly have access to data about where and when people are traveling to different parts of the city. In practice, however, this will be an interesting test case for the future of contactless payments in public transportation systems, particularly in the U.S. Will public transit riders really use contactless credit cards enough to meaningfully change the way that people pay for their transportation? And what can and will credit card companies do with the resulting data?

To answer these questions, a quick primer in credit-card speak is necessary.  First, because contactless credit cards don't require a pin number or signature -- or even the time it takes to remove the card from a wallet -- the "contactless" part is only usable for small purchases: the limit is £20 in the UK and $20 in the U.S.  Each card has an embedded chip which detects card readers without having to be tapped or swiped, as long as they are only one or two inches away. The chip technology that enables contactless purchases was created as part of a wider effort by Eurocard, Mastercard, and Visa to do away with magnetic strip credit cards; according to proponents of the technology, "EMV" chip-based cards are more secure than regular cards and could eventually carry multiple applications, like having a credit and debit card function on one card. (The broader set of 'contactless' technologies fall into the realm of near-field communication, often abbreviated as NFC.)

Figuring out how widely used contactless cards is tough. According to the UK Card Association, more than 30 million contactless credit cards had been issued in the country by the end of September 2012, and, not counting London's 8,500 newly-updated buses, more than 135,000 payment terminals have been installed. A report released in May by an independent research firm, though, indicated that only five percent of Brits have ever made a contactless payment, and millions of credit card users were "unsure" about whether their card had the technology. And though Visa tried to spark the contactless revolution during the 2012 Summer Olympics, the results were limp: the company admitted that only 150,000 purchases had been made with contactless cards during the Games. Moreover, according to a survey conducted by an ATM operating company, 55 percent of Brits indicated that payment hiccups during the 2012 Games made them less likely to support a "cashless economy," which is exactly the future that many contactless card proponents envision. 

In the United States, the story of contactless credit cards has unfolded a bit differently, and it doesn't seem likely that New York or D.C. are going to roll out direct credit card payments on buses or underground rail systems any time soon. Card companies and banks have introduced test markets for contactless cards in a few areas, like New York City, Atlanta, and Denver, and card companies report that millions of cards with contactless capabilities have been issued; but of the more than 5 million businesses in the United States, only 30,000 have the equipment required to accept contactless payments. Although the penetration of EMV chip technology has been slow in Europe, it has been even slower in the United States, and over the past year or so, almost every major credit card company has released an official plan of action for jumpstarting the use of the technology.

The bright future credit card companies see in contactless payments could be cut short by the rapidly developing mobile payments market, which tech gurus like Marc Andreessen see as a huge area for future growth. In countries outside of the U.S., this has certainly been the case: in just four years, 80 percent of people in Kenya started using mobile payments services, provided mostly by phone companies -- how's that for growth? According to the Communications Commission of Kenya, the number of mobile payments users has continued to rise in large part because of the lack of financial services in the country, providing an alternative form of banking for lower-income Kenyans.  

Here in the U.S., companies like Square, which sells a unique card reader that can automatically detect and take payments from any mobile device with its app, have also been making a splash in the market, albeit not in Kenyan proportions. In November, Square announced via Twitter that they're now seeing more than $10 billion dollars in transactions being made through their service, which does not even include the transactions that will be generated thanks to the company's new deal with Starbucks.
