I found it mildly entertaining that the same form also instructs you to "Never give out your password."
credit card number is always safe to give out. you have zero liability, and the fraud detection in the backend is far far far better than what fly by night app of the day does.
That assumes that the the cost of troubleshooting this, replacing cards etc is zero, which it isn't.
it’s almost zero. i am forced to replace a credit card due to theft about every 3 years. it’s not a hassle at all.
in fact you are forced to replace your card just due to expiry every 1-4 years depending on issuer.
