Update 28th July 2019:
Our partners have confirmed the cause of this TfL issue and have agreed to resolve this as soon as they can. Unfortunately, we have been told that their solution is expected to take another 5-6 weeks to put in place, so you will likely be unable to use your Dozens card for contactless travel over the summer.
Further details for your information:
Dozens’ debit cards have been caught up in a decision by the card issuer to stop accepting the cards of a financial provider called Loot who recently ceased operations, for “offline” transactions on TfL.
As you probably know, TfL is not able to check your live balance when you tap in on a bus or station, so they register your travel and only settle up at the end of the day. They therefore have to be reasonably sure that the cards they accept during the day will be valid when they request the payment.
To avoid any potential misuse of cards that should not be used, TfL were advised to block all cards that start with the BIN (Bank Identity Number) associated with those Loot cards.
This BIN is like a telephone number area code - each customer still has a unique number, but they are grouped together for administrative ease. While Dozens has absolutely nothing to do with that business, we happened to have the same “area code”, and unfortunately for Dozens customers, our cards were blocked too in error.
The systems used by TfL were unable to distinguish between Loot and Dozens, and therefore to re-enable our cards, these systems need to be upgraded. The work is ongoing and will need to be rolled out to TfL’s network. This will take time, and we have been advised it could take around 6 weeks for them to put this in place.
We know this is incredibly disappointing and frustrating as it affects all of our customers, including all Dozens staff who are also active users like you, and we have made this clear to all those involved.
Dozens will be making several changes as a result of this, including working on securing our individual BIN to avoid this sort of thing happening again.
There will be other changes too, and we will share some of these in the next few weeks.
For the time being, we are afraid that you will still be unable to use your Dozens cards for contactless travel on TfL. You can still use your Dozens card for all other transactions, and you can even use it to top-up an Oyster card instead. However, you may need to use a different card for travel for the time-being.
If you have any further questions, please share them here and I will do my best to answer these for you.
