I walked by the o2 shop in Chiswick last week and saw they’d changed their posters.
Both shop windows are now covered in o2 Money branding.
It appears to be like any other prepay debit card arrangement out there. Load money on to it and use it as much as you like. Only, it’s o2 branded. You do get updates and alerts through your mobile for every transaction though.
That said I thought I might as well put my money where my keyboard is. So I signed up last night.
I’ll let you know how I get on.
If you’re an o2 customer, you can apply for your own debit card here:
