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!
Next time someone calls me a maniac, I’ll show them this.
Definitely doesn’t live up to their username.
The fact it’s secured with a piece of sellotape is just *chef’s kiss*.
Peak Lemmy behaviour I love it
I just wanted to say your dad is definitely proud of you dude
You just had to 1-up everyone here…
I dissolved the card in acetone to extract the NFC chip and its antenna,
Wouldn’t the acetone also dissolve the insulation around the antenna wire? So when it touches itself, it shorts itself out, and – electrically speaking – you only have one turn of thicker wire?
Wire that thin is usually insulated with an enamel coating. I’d guess it’s either unaffected by acetone, or just tougher to breakdown. Allow the card to dissolve, but remove and dry asap, don’t let it linger longer than necessary.
Veritasium demoed this a few weeks ago while discussing tap-to-pay security and a vulnerability with apple pay+visa.
Well if it dissolved any insulation, it will not work, as the coil isnt even coiling. It is not a one big coil buy just two ends shorted(or as in the picture, a very small coil. Since this works i can only conclude coating does not dissolve in acetone
Ty, great idea will try it
Amazing, I have never thought of that! I have always carried my card behind the phone, which is a bit too thick for my liking, but this is such a great idea, thanks for sharing!
I am surprised that no one sells cases designed for exactly this
Fairphone 6 has an add-on exactly for this.
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.
What does this even mean?
Screen side with call buttons
Ah, now I see it. Thanks!
You could put the rubber bands in between the phone and the case, so it’s not on top of the screen.
Would be easy enough to print a custom case for this
Delete Plasma Mobile, get SXMO, disable touchscreen then accept calls with side buttons, ez
Or you can just keep your card in your wallet, like you have done for decades
The privileged have to invent their own problems.
Didn’t have to carry a phone for decades.
Now I don’t have to carry a wallet and multiple cards 🤷♂️
Gotta carry ID, what’s one more card?
I don’t carry my id and digital state ID s are out either way.
The problem is that I don’t cary my wallet with me for pretty much a decade now.
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.
I opened an account with starling partly because they have a real webapp, but you have to fucking log in with your phone, which is half the reason I want a webapp: because fetching your phone when you’re already at your computer is just a ballache
No website / desktop access?
Nope, the point of this bank is that it’s mobile only. No offices, no webapp.
Nope. The website says “get app” like 4 times. There’s a webapp but it’s for business stats only (like if you own a cafe). They are just trying to “appeal to the younger generation”, and one part of that is the app that spams emojis everywhere. Another part of that is furry stickers (“qr cat”) believe it or not; in physical, Telegram and Viber because everything in this damn country is held together by Telegram and Viber.
Now how about contactless payments without visa or MasterCard.
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.
At that point one should just https://dangerousthings.com/product/vivokey-thermo/ and get a free thermometer as well
Works without connection too🔥
Contactless payment works without connection. Now, the technical marvel is that it works even if the phone is dead.
This made me laugh more than I would’ve thought. Excellent meme. 10/10
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).
Can I use my Apple Card?
I’ve been using a magsafe card holder ever since I switched to GrapheneOS. Been working surprisingly well - I thought I’d forget my cards way more often, but it’s actually fine.
The only two negatives I’ve had so far is that my snake got her head stuck in my card holder’s finger loop once. And the powerful magsafe magnet fried the magnetic strip on a loyalty card I have in there, so the cashier has to type my customer number in by hand every time.
We may need pics of the snake.
I got a case with magsafe and a magsafe card wallet, that also works and you can have more cards too
Same, though it’s built-in to my phone, just needed the ‘wallet’ to attach
Man, this really makes me wish we had a more modern or powerful successor to the PinephonePro (that I could actually order from outside the EU)
I just don’t bother in the first place. Don’t like having a single point of failure.
