I recommend personally bitwala instead of wirex. Wirex has many problems, i got problems of card not loading and had to contact to support like 2/5 of the times i was loading the card.
Their platform is horrible and expensive, why to use it when you have better service providers available for example like bitwala. However bitwala requires identification for the card at least.
If you go for a card, do not go for wirex because you'll have to go through alot of pain to load few coins
