Don't believe the news.
Everybody in the US uses electronic payments for receiving their paycheck. Banks and utilities offer electronic bill pay. Mortgages are paid electronically. The US Government is banned by law from sending checks unless you're old, disabled, in a foreign country, etc.
Apple Card doesn't let you send in a check.
The majority of checks are business-to-business for relatively large amounts of money that would be uneconomical for card, but not big enough for a wire.
You most definitely can have ACH fraud. Page 10 and 33 and 41:
You don't need to go to the bank to deposit a US check. You open your smartphone app, take a picture. Businesses use check scanners. Or else stick it in the ATM, where it's instantly scanned.
The US checking system is universal. You can pay anybody with a check. That's why in 2003 it was modernized by Check 21 to allow checks to clear digitally. Essentially a check has become a digital transaction with an image file attached.
Europe had issues with checks because of differing currencies and differing national banking systems. That's why it was largely abandoned. Europe is only now transitioning to digital check clearing, I think the UK switched one or two years ago.
That's why checks in Europe and checks in the US are very different in terms of cost, time, and convenience.
