Here is the situation now, at least for Payoneer, I'm not sure how curve or other clients of Wirecard UK are handling this.
Funds in the cards are unfrozen, but you can ONLY use them with your card. Meaning you are allowed to withdraw cash in ATMs, checkout online and in stores. However, you can't withdraw funds from your card to your bank account (They are limiting the amounts withdrawn with this measure, because obviously there are ATM limits).
So basically they are allowing normal people to continue operating (which is great), but until July 6th, apparently the FCA is still investigating, and won't allow︀ bank withdrawal until that date.
Payoneer is allowing people to use their cards, but people︁ can't add any new money to those cards. All incoming funds are being held in︂ payoneer virtual balances ... Payoneer are saying they are working on ways so people can︃ "make payments" using those virtual balances in the near future (I'm assuming virtual cards maybe︄ I don't know), and of course way down the road find a new card issuer︅ or get a licence and issue cards themselves.
All in all, stituation still unclear, but︆ I really like what the FCA did. They allowed people who depend on the cards︇ to continue their day to day lives, while still holding back on big bank withdrawals︈ ..
