Registering credit cards online?

Is it possible for me to register my mother's credit cards online with a username/password, but yet not have to immediately link her checking account to them for paying the monthly bills? Basically, she doesn't know how to work the computer, but in a month or two wants me to help her to change her bill banking/bill paying over to online. I do all of my own banking, bill paying, etc. online. But I can't remember in regards to credit cards, if it's a "must" that you provide a checking account for bill paying, when registering a credit card online. She has some checks and such left that she'd like to use, so that they don't go to waste. So for another month or two, the payments to the accounts (even if the card is registered online) will be sent by mail. The Cust. Service people over the phone ask for only her income alone, for credit line increases. Online, it gives the option of "household income". I'd like to be able to combine our income so that she gets a better credit increase.

Why does she need an increase in her credit lines? This is raising all sorts of "red flags" to me. She can make single payments online w/o registering her checking acct(s). Also, why would she never need "paper checks" anymore?
Reply:It really depends on the credit card issuer. Every one is different. You might check the disclosures your mother received when she got the credit card (if you still have them) Otherwise, you might be able to find them online.





From personal experience, I know that HSBC does not require you to register your checking account when you sign up for online access, it's an option you can choose to pay your bill with - but on the flip side they do not take credit limit increase requests over the internet - only over the phone.
