But then you need to have money in the other checking account too.

Still, completely agree with your larger point. It's a big hassle having to switch cards, and the status quo (i.e., the industry being in a multi-decade transition period towards acceptable security) is sometimes the worst of both worlds:

Half of all merchants don't support automatic card updates and need to be manually fixed, while the other half do and have a chance of keeping your card alive in a fraudster's account where it's on file if your issuer is not careful.
