> well, there's the rest of the world, and there's the US, where chip cards are recent and still lack chip+pin requirement for now. And don't forget paper checks are still circulating. I didn't try last time I was there but I imagine that when you go to cash a paper check you go to a guy sitting by an abacus.

No, most(?) people cash paper checks on their phone. Or rather, using their phone.

Hardly.

Because swiping is so much more convenient. With a magnetic transaction I can just swipe and put my card away. Most of the time I swipe at the beginning of a long checkout (grocery store). With a chip transaction, I need to leave the card in until the very end. I now need to leave my wallet out, or put the wallet away and then remember to take the card back. More card readers are optimized for swiping with card inser…

This is NOT a consequence of chip card. In India, everything is chip and pin. Our ATM machines just need you to put the card in , chip side facing up and then take it out 2 seconds later (it glows green). Then you can put in your PIN number and move forward.

I think that's because ATMs are trusted devices, and only need a generic signed authorization to do anything. Payment terminals need to have the specific transaction amounts signed by the card, IIRC. At least that's the model I've learned here in my (European) country.

Does anybody know if using Stripe if we can pass the 2.9% fee onto our customers? We offer customized consulting plans that vary and typically in the thousands, so thinking of just adding a 3% credit card processing fee to the invoice for clients that use card. Researching around the net, it seems for traditional brick and mortar, some issuers don't allow you to charge a percentage based card processing fee. Any idea…

I use Square and Paypal for my business invoicing because you can send invoices that can be paid via credit card via email. I add a 3% card fee explicitly to all my invoices. No one any of these companies has ever said anything. I also offer the option of Bitcoin and wire transfer payments for invoices w/o a fee.

What annoys me is the expiry date and CVV. It seems like their solution to "more secure" is just to add more numbers. How about put the last 3 digits on the back, and call it the cvv ? How about use alphanumeric card numbers so we dont have to use as many digits ? Get rid of the expiry date used as validation. It's just more entropy, if you need more entropy then add another digit. It's just annoying having to type t…

Expiry date: It checks that you're not using an old card that someone has just thrown away, often card numbers remain the same if you get a new one. This is effectively just specifying the version of the card, and is something that needs to be on cards anyway (so the user knows when they're no longer valid). Additional benefit is that it means your customer has just checked that their card is still valid.

CVV: Not sure why it's on the back, but the point of this is that it's a number that's not raised, so it's not recorded when using a credit card imprinter (less common than is used now).

Yes, this! At least in the US, there is zero benefit to me as a consumer from chip cards. The banks have not increased rewards, or lowered interchange fees (thereby lowering retail prices). Federal law protects me from fraud no matter the card input method. Due to the risk of online fraud, I still have to check my statement for fraudulent charges. There are, however, noticeable downsides. Including everything coin me…

While federal law protects you from fraud, it's still extremely inconvenient to have your credit card skimmed and then likely automatically cancelled by your bank at an inconvenient time when someone tries to use it, and left without that credit card until the replacement shows up. Chip & Pin solves this particular issue fairly well. This is even more critical for debit cards being skimmed where it's actually a non-trivial process to get your money back.

Bitcoin fees are around 65 cents per transaction right now.

I think we can all agree the correct model is a card that generates a globally unique card number for each and every transaction (e.g. coin failed, final). It should also have a 2nd factor authorization like CVV which is not embedded in the magnetic strip (can't be read by swipers).

> swipe your card Sadly swiping is being replaced by chipcard.

> Sadly swiping is being replaced by chipcard. I see this being downvoted, and I'm wondering if it's not simply just misinterpreted. Most places in the US I've used chip&pin, the process goes like this: - arrive at merchant, select goods, get total. - look for a sign that says chip is not enabled. - failing that, move assuredly towards the chip reader and keep an eye on the cashier to ensure he or she doesn't move to…

There are a few local B&M merchants here that are using a specific model of chip readers, if recollection serves me correctly they're all readers from First Data, that are astonishingly fast -- at least compared to the all the others, which you've quite-accurately described.

Every time I go to the local mom-and-pop butcher shop I commend them on their chip reader's super fast processing speed -- and each time they comment that "Thanks, everyone says that!".

I find it incredibly funny and frustrating that their card reader is so fast, enough so that others have noticed & commented on it too, while everywhere else -- the local chain grocery stores for instance -- consistently have roughly >=1 minute processing times.

Also frustrating? The cashier has finished ringing my items up. I put my card in, select "No cash back", type in my PIN number, it thinks for a bit ... and then, it asks me if I want to confirm the charges?! No, I don't, I just typed in my PIN for kicks! I get it, it's to verify the amount, but I'd love to know what percent of the time a user [intentionally] selects "No" at that screen -- I probably _accidentally_ select "No" about 5% of the time, and roughly 0% of the time have I ever intended to select "No". Small things, but annoying UX overall.

I'd think that many larger chain retailers are working on this. Some may have it solved w/ more "proprietary" systems; I don't shop at Target much lately, but I recall their payment UX being superior to most, unsure if their chip system is too though.

I'd love to get the speed of swiping back! :-)

We work with Stripe exclusively, and offer credit card or ACH invoices. ACH we don't charge any fees since the maximum fee from Stripe is $5. Credit card is another story since our invoices are in the multiple of thousands (2.9% adds up).
