I’m a buyer and made a couple purchase last night on Etsy. All my credit card info was saved on checkout with no verification required to use the card. Surprised me in comparison to how Amazon or other retailers typically require the full card number be re-entered on checkout. I understand this is different but seems like a bad convenience trade off.

Amazon doesn’t require re-entry of any details on checkout, at least in the US. I can click a button and immediately purchase something with minimal confirmation.

I have never had to confirm any details with Amazon as far as I can remember.

I'm in Canada and I've had to confirm details on my card. I guess outside US thing.

In the US, you do have to confirm the details on your card when you change your shipping address in Amazon, or you need to make any updates to it (i.e. cvv / exiry date). Otherwise, not so much.

Edit: Oops, just noticed that point was also posted twice in sibling comments. Oh well, third time's the charm I guess?

I'm from Canada too. The only time I had to confirm my number / CVC was when I changed my delivery address.

You do have to enter additional information when signing in from a new browser.

If you change your shipping address, it will ask you to re-authenticate the credit card number.

Plenty of sites, including Amazon, do not require you to re-enter a saved card number.

Some sites only require re-entering the card when shipping to a new address.

Yah I think it's a good thing. I have a password manager so it's only a few clicks to paste the card number in. I'm guessing the majority of consumers are annoyed by it.

This is what Amazon does, in my experience.

amazon has required me to re-enter card numbers when shipping to an address not associated with that card. I have bought on Amazon in the US, Spain and Mexico with this happening each time.
