Which method of paying bills makes you feel more secure, mailing away a cheque or paying online with a credit card?

I feel more secure paying bills online using my credit card. I like getting an immediate confirmation and that I see it right away on my online bank account. Putting a check in an envelope and sending it out into the wide world makes me feel very nervous! My mother on the other hand feels exactly the opposite. Using her credit card online makes her skittish, she’d much prefer to mail away cheques.

What about you? And do you think it’s generational?
