I'll do one better:

My payment card was just a bit too wide to fit in my cellphone's cover. The phone's own NFC antenna is at the top - and I use it all the time - so the card had to be at the bottom of the cover to avoid triggering the phone all the time, in portrait orientation so-to-speak.

So I dissolved the card in acetone to extract the NFC chip and its antenna, then carefully reshaped one end of the antenna so it's a bit less wide (and since I couldn't modify the length of the wire or the number of turns in any way to avoid de-tuning the antenna too much, I sort of accordioned one side of the rectangle to accommodate the extra length of wire).

Then I set the new shape of the antenna permanently by carefully applying a piece of packing tape over it, flipped it over, taped over the other side to seal everything, then carefully cut around the new, ultra-thin, stubbier contactless payment "card".

Now it fits really smartly in my cellphone cover!

Take that Android! This works even with the phone powered off! It works even without the phone at all!

Wait...

Or you can just keep your card in your wallet, like you have done for decades

Ironic it's a monobank card, it's mobile only and you have to use a locked unrooted googled phone (or an iPhone) because big brother said so.

Now how about contactless payments without visa or MasterCard.

monobank

We can go even further and create some sort of physical tokens that we can give to each other. These token would be secure, completely private, waterproof and even work offline. Maybe we could even put some pictures on them and make them vision-impaired accessible - the possibilities are endless!

People forget that cash is a technology - a pretty good one too.

Maybe a solution similar to this could work: https://github.com/nfcgate/nfcgate/blob/v2/doc/mode/Relay.md

Have the card at home sitting on a reader connected to your homelab, add NFC module to PinePhone and simply relay the traffic over network.

Nice meme, but for us out there with at least a fully virtual card (some companies provide such benefits), we need a real MyAss-Pay alternative

I recently found Walt, but it's a work in progress for now. The app is avalaible though

Works without connection too🔥

Some banks issue stickers for phones without NFC. It's another physical card but contactless only and very thin (probably with an aluminum strip antenna).
