Apple Pay on Transport for London - need full Device Account Number
I'm curious to know how Apple Pay will work on Transport for London. Following is the current situation:
- Anyone can use a contactless payment card (debit or credit card) on the yellow card readers at the beginning and end of each journey. TfL's system calculates the fares for multiple journeys and then charges the payment card at the end of the day. Fares are subject to daily and weekly caps, so it never costs more than buying a daily or weekly Travelcard. Passengers can optionally register their payment card number(s) on TfL's web site in order to see detailed journey histories. Seeing one's journey history is essential, particularly if touching in or out at the beginning or end of a journey fails, which is a frequent problem. If a touch-in or touch-out fails to register, then the passenger is heavily surcharged for an unresolved journey (because TfL assumes the worst case of a long journey) and the passenger then needs to claim a refund online.
- Apple Pay users (currently possible only with a US credit card on an iPhone with the region set to the United States) are already using Apple Pay on TfL according to the Daily Telegraph.
One thing we already know about Apple Pay is that it doesn't give the payment card number to the retailer. Therefore TfL won't see the passenger's payment card number for each Apple Pay transaction. Therefore how do Apple Pay users (including existing US-based users) register to see their detailed journey history on TfL's web site? I asked TfL who said I need to obtain my ePAN from my card issuer (PAN stands for Primary Account Number, industry term for a card number). TfL mentions the Device Account Number, which I understand is the ePAN.
Although I'm a UK-resident Brit, I happen to have a US-issued American Express card, which I've successfully added to my iPhone 6 for Apple Pay. It shows my Device Account Number, but only the last 5 digits are visible. I've no intention of using my USD-denominated Amex card for GBP-denominated transactions, so I'll wait until my UK-issued Amex cards are supported next month, but I nevertheless need to know how I will see my journey history on TfL's web site when I start using Apple Pay on TfL. I asked Amex US, who said that the Device Account Number (or ePAN) is a 15-digit number (same length as an Amex card number), but it would take a month for Amex US to obtain it from Apple. I asked Apple, who said that the Device Account Number is not stored on its servers. This contradicts Amex US, who said they would need to obtain it from Apple; I believe Apple over Amex in this case.
The lack of online journey histories, and the consequent inability to identify and correct unresolved journeys, will be a big problem for those using Apple Pay on TfL. If it is so difficult to obtain one's full Device Account Number or ePAN, this will be a significant impediment to using Apple Pay on TfL. Does anyone know how this is going to work?
