He’d have to risk bumping noticeably up against your pocket, or dipping his terminal right into your bag next to your wallet, with a maximum return on his risk of £20 each time.

The idea is that the risk/reward odds for a crook with a portable “transaction harvesting” terminal should be stacked against him. The maximum value of any PINless transaction is deliberately kept low.The “Near” in NFC limits the range at which your card will work.In marketing jargon, the transaction is made frictionless for your convenience, with the risks kept in check because: typing in your PIN) when the amount you’re spending is below £20. The bank, the merchant and the cardholder (that’s you) effectively have a arrangement to forgo the second factor of authentication (i.e. This works because, for small-value transactions, the card and the terminal agree that they won’t ask for your PIN. In theory, then, a crook could work the payment the other way around, by waving a suitably rigged payment terminal near your card, telling your card it wanted to buy a Caffè Americano, getting it to approve the transaction, and pocketing the cash. The data is received, processed and transmitted without any physical circuit between the card and the terminal. → Typically, you have to get your card very close indeed, perhaps even tapping your card onto the terminal, but you don’t have to slide or insert the card into any sort of slot.

The antenna functions as an electrical generator coil to start with, and then as a regular antenna for the rest of the process, which typically takes a fraction of a second. That’s enough to wake up the card’s chip, which then reads in some data wirelessly, performs various cryptographic calculations on it, and sends back a reply.
These let you authorise payments simply by waving your card near a suitable payment terminal.Īs you pass your card through an electromagnetic field generated by the terminal, a coiled-up antenna buried in your payment card produces a tiny electrical current. Paying without touchingĬontactless bank payments usually rely on Near Field Communication (NFC) – the same sort of electronics used in public transport cards such as London’s Oyster or Sydney’s Opal. Very greatly simplified, it’s a special sort of Man in the Middle (MitM) attack that could, at least in theory, be used to trick the owners of contactless payment cards into spending enormous sums of money without realising it. It will be presented on Wednesday 05 November 2014 at the 21st ACM Conference on Computer and Communications Security in Scottsdale, Arizona.
Their paper is ominously entitled Harvesting High Value Foreign Currency Transactions from EMV Contactless Credit Cards without the PIN.

No wonder the prime minister wanted to talk about the vaccine.įor Boris Johnson and the nation, everything now rests on the vaccine's success and how swiftly it can be administered.
Those frightening figures, at the start of lockdown three, are eye-watering compared with those in lockdown one, back in March. Yes, that's right: A million infected and one in 50 of us with the virus. The prime minister will be relieved he wasn't challenged too much on the boffins' alarming new figures that more than a million - one in 50 - people are now infected. He said the public should not expect a sudden relaxation of the COVID-19 rules, with restrictions "progressively" eased instead.Īnalysis: For the PM and the nation, everything now rests on the vaccine's successīy Jon Craig, chief political correspondent He said he had "no choice" but to plunge England into a third national lockdown, and vowed to use "every second" under the stringent restrictions to put an "invisible shield" around the elderly and vulnerable through the mass vaccination programme.Įarlier, Cabinet Office minister Michael Gove told Sky News the government "should be able" to begin easing England's coronavirus lockdown in March. The prime minister said he believes that by the middle of February there will be a prospect of relaxing some of the measures - but he warned there are "lots of caveats built into this". The latest shutdown to try to control the spread of COVID-19 was announced yesterday.
