I thought the same with Pockit but alas it's not so. The second card you get just has a customer number, not a long card number, sort code or account number. I asked the customer service rep when I phoned how you would pay money into the 2nd card and he said you can only pay money into the main account and then transfer the money into the sub account. Which defeated the point of me even having the pockit account for SW work so I'm still on a search to find safe deposit options once I can start working again after the threats I received this week.

Aaah, thank you for clarifying, Houdini. A bit of a bummer.
I was just getting excited about Pockit and wanted to set up the main card for business materials and the sub card for advertising under a disguise...
