Hi Dan,
It is definitely something we are thinking about, but haven’t decided on yet 
. Opinions differ within the team about whether it is worth doing, but if we did do it, there are probably some ways we could manage it without too much involvement from our card manufacturer 
. It is also worth mentioning that if we do decide to go for it, it is very unlikely to happen pre-banking licence.
I am interested in how many people would want this, so thanks for sharing your interest! 
Thanks,
Natasha
