Contactless on the tube and rail
In message , at 16:13:19 on Wed, 17 Sep
2014, Mizter T remarked: So TfL owns the right to the MiFare system, smart card readers and contactless bank cards does it? Umm , no. So what is left - the gates and the and the backend software? They own whatever middleware and other technology has taken over a year more than even the most recent estimate to get running. It looks as if it *ought* to be simple, but clearly it's not. You think it's simple. OK, if you say so. I said it LOOKS as if it OUGHT to be simple sigh, but clearly it isn't. That's not the same as saying IT IS SIMPLE and that they've botched it. Right, I'll rephrase then... You think it looks like it ought to be simple. OK, if you say so... If I can by a coffee at Starbucks by waving a CPC, and it ends up on my bill at the end of the month, it does seem as if waving a CPC at a gate ought to register my presence with enough information to bill me overnight once I've also registered a touch-out. But clearly it's all a lot more complicated than that, given the kerfuffle to get it all in place. -- Roland Perry |

I wonder how they (or the bank) deals with a card that accesses an account with nothing in it and no overdraft allowed. Does the bank have some sort of "special" overdraft for that or do they just refuse payment and the vendor is out of pocket as can happen with credit cards? -- Spud |

contactless. This is especially difficult as many (USA at least) tourists arriving in London will have bought one of the latter at the airport (where they are marketed aggressively) in order to get over the C&P thing where their cards may not be compatible, and of course in order to have their money in their pocket in Sterling. Does the bank have some sort of "special" overdraft for that or do they just refuse payment and the vendor is out of pocket as can happen with credit cards? On the other hand, TfL has gone out of its way in the past to say that certain foreign issued and prepay cards won't be accepted. But it's not clear if they mean "because they aren't contactless - duh!" or whether they fail TfL's risk management tests due to the possibility of being dry. Now that CPC is fully rolled out, I expect we'll see more information about both TfL's position on this issue and also war stories from disappointed would-be travellers. One possibility is that while they won't be able to get a balance from the bank in the milliseconds it takes to touch in, maybe by at least overnight they'll know to blacklist such a card's future use. -- Roland Perry There are two different types of contactless cards around: i) just emulates the magnetic strip ii) is connected to the EMV chip. It's the first (mostly USA issued) which won't be accepted. |

To do with technology rather than what sort of credit rating you have. -- Roland Perry |

That has sections which look (without me speed-reading the entire 252 ages this evening) like the ones I earlier said I recalled which showed that nothing [for example where, when, what for, and how much] can be *written* to the card by the merchant during a contactless transaction. Are you familiar enough with the document to be able to confirm or deny this? -- Roland Perry |
