I've been using Wirex for a few years now. I can store cryptocurrencies there (I prefer Stellar XLM because HIVE is unavailable there), while paying in the store they are converted to FIAT. This is the only solution of this type that I know. Many different FIATs are supported. The advantage is that if the crypto market is growing, I can hold cryptocurrencies on Wirex and when paying, only the amount needed to make the payment is converted. Fees are at an acceptable level. Wirex card (MasterCard) does not support GPay so I use Curve as an intermediary. Wirex is connected to Curve and Curve is connected to GPay. The duration of the operation is more than satisfactory, the whole thing takes only a few seconds and so far I have not had any problems. On X dot com you will find a lot of objections about Wirex, especially about the support, but so far I can't say anything bad.

But you know very well how to get rid of the affiliate part of the link :)
So you use your Wirex card to pay at regular shops with regular credit card terminals?
Yes, actually I pay contactless with smartphone, holding crypto instead of FIATs all the time. So it's like I'm paying with crypto everywhere.
Cool! I just read an article that Wirex came out with W-Pay, a non-custodial solution that uses SK Tech and Polygon to allow users to have complete control of their funds while using the Wirex card.
Yes, it's a new solution, but I haven't recognized it properly yet.
