Credit Card Security

credit card number is always safe to give out. you have zero liability, and the fraud detection in the backend is far far far better than what fly by night app of the day does.

Same reason that you still keep credit cards around; security. When money becomes involved you don't want the device doing the authorization to have any way to be influenced by the one requesting it.

Yeah, Chip and PIN (EMV) in the UK is much better for security, we have a lot lower rates of card fraud here than in the US. In fact most of the world has now switched to EMV, the US is the only major country that I can think of which is still on swipe payments.The problem goes further than the cards themselves though, I think the big problem with them is that you have to give companies all of the details needed to make a charge when you buy things online, and those details are stored.

I believe there's a price limit on it, it's mostly for small transactions. Also, pre-chip cards only need a signature, which is easily faked. Most bank insure your card.

The security from credit card is FUD. If anything, it's probably less secure:1. Users are encouraged not to care about the security as they are insured - which means spending in dodgy online stores.2. Magnetic stripe technology is terribly insecure.Combine the both and you end up Americans being prime target of fraud, constantly (rightfully) scared of Eastern European fraudsters. Meanwhile people here in Europe never ever worried about it.

at least for mastercard this is true: as per my banks tos i have to take care that nobody gains access my 'securecode' and i am liable for any unauthorized charges. (because the 'securecode' is supposed to guarantee that it is me who is using the card)

Chip transactions are indeed a huge signal - a chip transaction can’t be faked due to strong cryptography. Granted, the card can still be stolen, but it’s rare enough that most banks let it though.

Isn't that what a chip does, which basically all modern credit cards have in the US now?And all my major credit cards also allow me to generate one-time use numbers to use online, which I need to sign in to generate using 2FA.Finally, I've never been "blamed" for fraudalent transactions. They've happened but I've never had to pay, nor do I know anybody who has.So really not sure what you're upset about?

Payment is more of tamper resistance and trust problem than protocol problem. You don't want a hackable card tied to your credit.

Rather than straight cash, using it as a more-secure credit card would be enough to sign me up. It would prevent card skimmers, people copying numbers, etc. They could generate one-time card numbers for online purchases at existing merchants. Despite lots of mitigations, VISA/MC still have huge fraud problems. This would give them a new tool to lock things down.
