It would have been nice if crypto didnβt turn into a network of pyramid schemes.
Like, I am sympathetic to the idea. I mined a Bitcoin a long time ago (and lost it in intervening years). But holy moly, did it erupt into a tire fire.
Non American credit cards when
I'm European, I technically have a MC credit card which I'll use on the rare occasions I need a credit card, but the vast majority of the time it's debit card or direct transfers (what they're now calling wero).
Works without connection tooπ₯
Contactless payment works without connection. Now, the technical marvel is that it works even if the phone is dead.
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!
Peak Lemmy behaviour I love it
Wow.
"Please use chip reader".....
Have you ever run into difficulty with needing to authenticate with chip+PIN? Like while traveling?
That would be my big with with this; it would make it very difficult to pass a PIN check, to say the least!
Super cool idea. I might just try it myself and see if I run into issues.
What I modified was in fact a contactless payment token. It had the form factor of a payment card, but it only does NFC.
I have another card for chip+pin.But I almost never use it where I live, because all limits were lifted on contactless payments a few years ago. If I try to pay something really expensive contactless, it will ask me for the pin - which is specific to the payment token.
I just wanted to say your dad is definitely proud of you dude

You just had to 1-up everyone here...
Next time someone calls me a maniac, I'll show them this.
Definitely doesn't live up to their username.
Kudos for the effort. With that said, this would definitely raise some eyebrows if you have to return the card when getting a new one.
I've never had to do that... Just say you lost it.
Depends on how fussy the bank is, but yeah.
You are fucking crazy. I love you.
The fact it's secured with a piece of sellotape is just *chef's kiss*.
You clever, I like.
I am surprised that no one sells cases designed for exactly this
Fairphone 6 has an add-on exactly for this.

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
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.
this can be useful too! https://f-droid.org/packages/de.tu_darmstadt.seemoo.nfcgate
probably requires root though
At that point one should just https://dangerousthings.com/product/vivokey-thermo/ and get a free thermometer as well
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).
Or you can just keep your card in your wallet, like you have done for decades
