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 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.
Banks are closing ATMs left and right. It is getting increasingly harder to withdraw paper money and it sucks.
I haven't noticed, but my grocery store recently limitted their cash back to $40, so you have to split your purchases into separate transactions until you have the cash you want.
Basically a straight upgrade from all the people (usually women for some reason ? Small/no pockets was the argument my gf made) who keep their credit card in the back of their phone case and also have apple pay set up.
This made me laugh more than I would've thought. Excellent meme. 10/10
Now how about contactless payments without visa or MasterCard.
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.
Even without the greater fool scam, it's basic physics that a some dedicated servers will be more efficient than having every computer in a distributed network process every transaction.
And authoritarianism can be more efficient than democracy. Doesn't mean I want authoritarism though
Itβs not democracy though.
Whatever the ideals of cypto are, however user friendly could be made, in reality, itβs just fundamentally too easy to be abused.
As-is, itβs one of those βit would work fine if everyone learned it in detail, and grifters would go awayβ ideas, and thatβs not going to happen.
Democracy is fragile and exploitable too, but it has a track record of working across general populations for reasonable lengths of time.
What kind of abuse are you talking about? I doubt you're talking about a 51% attack, which is incredibly hard. I'm guessing you are talking about social engineering, like where some scammer gets a poor soul to leak their bitcoin wallet or something like that.
In these cases, yes a centralized payment system can be useful, because the authority in charge can just reverse transactions that are deemed fraudulent or the result of a scam. But that same authority can do things like ban all payments to Steam for porn games (like the recent Visa Mastercard drama). That same authority can say "GrapheneOS and Pinephone users aren't allowed to make NFC payments".
In cases like these it would be nice for there to be an alternative to centralized systems, at least for those technologically literate enough to use these alternative systems.
GNU+Linux is currently being used to kill civilians in several wars, but we don't feel the need to point that out every time somebody says they use Arch btw.
Good tech can be used by bad people without everybody having to distance themselves from the tech itself.
That's not to say that BTC is good tech, but it's a decent proof of concept to free digital transactions from monopolists and tyrants.
Non American credit cards when
France has the national CB system, independent from American systems. https://en.wikipedia.org/wiki/CB_Bank_Card_Group
A lot of European countries have their own debit card networks. Germany has GiroCard, Italy has PagoBancomat and so on. The problem is that those are national systems that stop working once you cross a border. Most cards are therefore cobadged with Visa or MC as a fallback system.
What's needed to get rid of the cobadging (at least within the EU) is some kind of translation layer to bring the existing European systems together.
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).
Unfortunately Visa and Mastercard also own the payment network for debit cards in many countries in Europe.
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!
That is serious dedication.
Peak Lemmy behaviour I love it
Next time someone calls me a maniac, I'll show them this.
Definitely doesn't live up to their username.

Have you ever run into difficulty with needing to authenticate with chip+PIN? Like while traveling?
That would be my big concern 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.
Do you mind if I ask what bank issued those? Why? Does the chip+pin also tap or are they features on totally separate cards?
I've never heard of a separate tap to pay token (outside of perhaps transit passes or like, arcade cards), and never a card based tap transaction that asks for a pin.
Payment tokens are very common. Usually they're sold as keychains, wristbands or rings, and they're provisioned to work with the myriad of payment processors out there - which aren't banks.
in my case, it's a token from iCard. The way it works is, it's connected to a regular bank account number with an IBAN number (supplied by iCard when you activate the token), and you transfer money to it that you can then spend with the contactless token. The nice thing is, if you lose it, you can't lose anymore money than you put on it.
I just wanted to say your dad is definitely proud of you dude
The fact it's secured with a piece of sellotape is just *chef's kiss*.
You are fucking crazy. I love you.
You just had to 1-up everyone here...
Works without connection tooπ₯
Contactless payment works without connection. Now, the technical marvel is that it works even if the phone is dead.
Or you can just keep your card in your wallet, like you have done for decades
Take that Android! This works even with the phone powered off! It works even without the phone at all!
Wait...
