Don’t worry guys its only for specific high-danger events like ‘crowded areas’, easy enough to avoid

I think people who’ve had bank accounts frozen or seized by their government for attending a protest might disagree with you

I haven’t tried them for online shopping yet.

They mostly work from what I’ve used, but since websites are able to tell them apart from regular credit cards it’s up to them to decide. YMMV but most subscriptions won’t allow a prepaid card to be used as payment, but for one-off purchases they typically work fine

It is getting worse though. I’m getting more and more “payment processor declined card” errors while using them even on sites that used to accept them. I think in the past they’ve been kinda obscure but now they’re rising in popularity as people try to protect their privacy. And so more sites are cracking down on them

It’s kind of like VoIP numbers. They used to work for SMS verification everywhere but now it’s pretty rare to find any website that won’t detect and block them

In this day and age if you don’t see the value of a decentralised currency that no government can control, you’re very naive

It has to be a mobile device with a phone number. When I tried this out a while ago the QR code prompts your phone to open its SMS app to send a text message. It can’t be opened on a desktop
