I moved from checking to credit specifically because I didn’t want someone gaining direct access to my checking account. It doesn’t have anywhere near the checks and balances or alerts that my credit card does. And if the credit company detects an anomaly, they ship me a new card number the next day. Easier than migrating everything over to a new checking account number, and more secure.

The reason you don’t see the checking account number compromised is that people don’t give it out.
