I use contactless chipped card everywhere and it literally takes less than a second for most payments.

I am not going to use such an insecure payment method.

What's insecure about it? Heard of a lot of cases where money were stolen from people banks accounts/cards using scamming, viruses etc (and witnessed one right when it was happening), never heard of problems because of card being contactless. It also lets you not to flash your pin in front of the whole store for many of the payments. I think on the convenience/security scale it's very high.

They limit it to low value transactions specifically because it's not as secure. Feel free to dig into it if you don't trust the industry's assessment.

They limit it to make it secure and make it pointless for the thieves to try exploit it, at the same time covering many quick payment needs - convinience/security balance I mentioned and you ignored. And feel free to think about industry's assessment - they make more and more cards with contactless payment capabilities and it's used very extensively in some countries of the world already.

to make it secure Security is not binary. It's trusted less than physical contact readers for large value transactions for very good reasons. They care less about low value transactions, but that's not a security question.

You may not care about security, but all I said was it's worse, and not good enough for me which you have not denied.

Apple Pay takes all of about two seconds. No way you are paying with cash faster.

Paying for lunch is pull out cash and go vs. handing card to waiter waiting on them then signing and go.

In that case cash can save ~5 minutes.

That was true before the introduction of chip cards, though. The waiter's having to carry the card to the staff area of the restaurant, complete the transaction (by swiping), then return the card to you, probably interweaving some of their other duties along the way, took up most of the time. Their having to wait an extra few seconds for the chip reader seems a drop in the bucket.

I noticed this process has gotten noticeably longer after chip cards where required.

Waiters used to take cars and swipe them ASAP presumably to get better tips by being prompt. Now, put this off until they finish a full round and/or put cards in and start doing something else because it's going to take a while.

Granted, this is far from a complete switch, but it was still noticeable.

You don't have to hand anything over with near field stuff. You put it near it, ding, done. Saving you 5 minutes + time it takes for you to exchange cash. If you're dealing with a waiter for lunch, you're already wasting a ton of time.

The trade off on what food I eat is not a waste. Wasting time on slow payment methods when better options exist is.

Near field is also limited by transaction size so it's far from sipe for anything.
