The principle is also using the bank's money, not your money. So you make a purchase and now you owe the bank. Unless I am very strapped for money or there is an incentive program, I see little use in using one.

Dutch here. We don't have points or cashback. Purchases are insured with standard bank debit payments as well, as are chargebacks. I do own a credit card but that is purely for the occasional (usually US) webshop that doesn't accept European debit cards, or as a backup payment method on vacation (my debit card once broke on vacation and my family had to send me money through Western Union)

The only time I ever use a CC is when I'm dealing with an American company- because it's either CC or PayPal with them.

Visa and MasterCard debit should work anywhere online regardless of origin.

These cards don't have a 16 digit card number and CVV that you can in online shops and pay with those. This has the advantage that these numbers also cannot be "stolen" and then used by criminals to buy things.

Debit cards are really just for physical payment, where you either use contactless payment or by using a PIN. For online shopping, the shops talk to the banks by using an OAuth-like API that can be used to either pay once or set up a monthly payment. There's a few different of these APIs throughout Europe, in each country usually only 1 or 2 are used. Some examples of these APIs are: Bancontact, iDeal, Giropay and Sofort

European webshops usually only support the ones in the country that they are located in, and for all others they either support credit card or bank transfers (which are free and standardized within Europe). American webshops usually only support credit cards, so that's the most common reason for people to have one.

I worked for a points loyalty program, and the customer always pays. The bank knows their market well, they know the redemption rate of points for different demographics and they set the annual fees on points earning cards appropriately.

For a small number of very diligent points hack customers, the bank loses money on this and the customer wins. For a larger proportion customers get back roughly what they paid in fees.

Then for the remainder the points eventually get written off or redeemed for value that is far lower than the fees they paid.

When you pay off the card, it can automatically debit the Apple Cash account first. Basically all my purchases are 1% cheaper on that card than my other ones. Sure, spending $9,900 instead of $10,000 doesn’t sound like much, but it’s painless free money.

The first 3 don't really seem to exist in relation to CCs in NZ, and wanting/needing to do a chargeback seems unlikely.

There are probably mild benefits to me having a CC over a debit card in NZ, but it doesn't seem to be anything like the US.

Chargebacks atleast exist in NZ - this is what I mainly use credit cards for - if the company goes bust before delivering (or before you take a holiday etc), or the product isn't as described, or the company starts quibling about their unconditional money-back guarantee - the credit card company will pay (by law)

That's my main reason for never using my debit and always using a credit card, to offset the risk of fraud.

It seems like a few of them have some perks like travel insurance, cashback or airpoints/reward points, but most of them have no or very tiny perks on their cards. A lot of the airpoints are also locked behind a minimum spend in the first 3 months.

For me personally even the "good" cards aren't that great because I just don't spend that much money. Though travel insurance would be nice once the world opens back up.

Chargebacks are useful depending on consumer protection laws. I'd guess in NZ they're less useful like here in Aus, but if you buy from foreign companies it can be a useful stick to wield as otherwise you'd have little legal recourse.

I've got reasonable travel insurance protections when I pay with the CC, I get airpoints, and some chargeback options, as well as fraud detection. Additionally, it's been easier and more reliable to set up online payments with a credit card.

Some banks might ask you to contact a merchant before trying a chargeback, but if you don't get your money back the bank will either do a chargeback or cover the cost (as they do with fraud).
