Just remember that if you convert these dollar percentages into decibels, you must use the factor 10, since money is power.

Surley it would not kill the IT guys at your card processor to issue cards that can only be used in a given territory? Or at least, a transaction would not be authorized out of bounds?

I sure wish that card issuers / banks would join the modern world and make MFA (Multi-Factor Authentication) available. You stick your card in the payment terminal thing at the grocery store and your mobile phone prompts you "Authorize payment of $83.53 to Fat Goose Groceries and Wine? Authorize / Decline / Report Fraud". Yes, I understand there are problems with implementing that but use of machine learning could auto-approve your nightly pint at the pub, weekly laundry at your dry-cleaners, but then prompt you when you buy airline tickets or jewelry.

It might take an upgrade to the payment terminals but they could use OTP (One Time Password), like those RSA fobs that display a different numeric code every 60 seconds, or the Google Authenticator app on your phone. You put your credit card in the payment terminal, click OK on the terminal, and then the terminal prompts you for the code from your phone app, which could be done via scanning a 2D barcode on your phone like your boarding pass when you fly. That would prevent problems related to "I can't get a cell signal at the checkout".

MFA would stop remote credit card theft cold because without the cardholder's phone, the credit card would be useless. Card issuers / banks know all this but they've run the numbers and tens of thousands of transactions from stolen credit cards every year (and the heartburn that it creates for the victims) is cheaper for them. Now you've got me ranting about the banks.

"Why is it that everyone that knows how this country should be run is cutting hair or driving a cab?"

Or join the even more modern world and use a phone app together with NFC, obviating the card.

Saw a US project for sanitising the number pad on card terminals with UV. Around here contactless payment has been around for a while and boosted by C-19.

Keep my coffee warm, I will run home to reply to my email to authorize this payment.   Really, I will be right back because I really need my caffeine fix.  Really ... I'll be back...
