At least in Canada, non-cash transactions are not rounded. There's no need nor justification to round credit-card transactions.

Yes, in the big scheme of things, the savings are tiny. But pennies are really annoying and most end up in jars or drawers somewhere rather than circulating anyway. So might as well ditch them and the tiny savings is just a bonus.

We'd be drawn-and-quartered instead.

You just round the final total to the nearest 5 cents if someone pays cash. That is what happens in Canada.

Electronic boarding passes are fine, if they're just bar codes in a PDF. Then people with smart phones can use their phone, and people without can print them.

Forcing people to use an app is simply trying to spy on them.

Ah yes, reminds me of the bad old days of the first PDP-8 virus:

"Your bank account has been compromised. To restore security, toggle in the following sequence on your PDP-8 front panel: 110101-010010 111110-000000 ..."

On the one hand, I think music copyright collectives can go a bit overboard (watch some of Rick Beato's YouTube videos where he talks about copyright abuse.)

On the other hand, anything that can damage the parasitic generative-AI industry makes me happy... so... yeah.

Nobody, but nobody, predicted this, right? /s

I hope the AI tech bros are watching. They're the next Neom.

Wow, you are grumpy. Who hurt you so much?

OK, boomer. And great that you find it easier to track credit card transactions than account transactions, because they are so very different.

That is not how it works. It's a chip-and-PIN system and the merchant never gets your bank details. Payment technology has advanced in most places outside the USA.

When you do an Interac e-payment, once again neither sender nor recipient knows the other's bank details. All of that is known only to the banks themselves and Interac.

In Canada, it is expressly permitted to offer a cash discount. This right overrides anything a card processor might try to put into its contract.

In Canada, we have the Interac e-payment system that uses your debit card, and has extremely low merchant fees (between $0.02 and $0.06 per transaction.)

You can also send Interac e-payments from your bank account for free with no charge to the recipient either. They are fantastic!

Back when I ran a business, we accepted Visa and MasterCard, but not Amex because of the ridiculously-high fees to accept Amex. It didn't hurt our business.

I would much rather see businesses charge the excess fees to customers than outright reject cards. Use a bog-standard VISA or MasterCard? You pay list price. Use a rewards card whose merchant fee is 1% higher than normal? You pay a 1% surcharge.

This eliminates market distortion and makes people rationally choose the tradeoff between a regular card and a rewards card.

Clearly, Meta is wasting its time investing in AI. It would get a far better return on investment if it redirected all that cash into finding better ways to scam. After all, scamming has been proven profitable.
