Credit Cards

Dear Liz: Can you please explain why a personal identification number is not required when one uses a credit card? I know people who’ve had their card stolen and used quickly and for large amounts. That would immediately protect the credit card company from paying millions to cover losses.

Answer: “Chip and PIN” cards — which combine a microchip with a personal identification number — are the norm in most of the rest of the world. In the U.S., however, credit card issuers are reluctant to require their customers to use PINs.

The issuers are worried people would find the PINs to be a hassle and would opt to use a competitor’s card that didn’t require remembering and entering a number. The massive amount of fraud that results is considered a cost of doing business.

Consumers aren’t on the hook to pay for these bogus transactions as long as the fraud is reported within 60 days of the charges appearing on a statement. But compromised cards are still a hassle.

One of the best ways to protect your credit cards from fraud is to use mobile payment systems such as Apple Pay or Google Pay. These systems don’t expose your credit card number to the merchants and allow you to pay for purchases quickly and securely.

Dear Liz: Following your advice on building credit, we recently added our son as an authorized user on one of my credit cards. My question is, what happens when I pass away? Does the card remain with him as the only user? Do I need to address this in my will?

Answer: Your executor, the person you named in your will to handle your estate, will be responsible for closing the account when you die. If there are any balances owing, the debt will be paid from your estate. There’s no need to make special provisions for the account in your will. By that time, your son, one would hope, would have cards of his own, so the closure shouldn’t affect his credit scores much if at all.

Dear Liz: You recently wrote that using more than a small percentage of your credit cards’ available limit can hurt your credit scores, even if you pay your balances in full. I pay my credit cards in full each month and I also make several payments (via my bank’s online payment service) during the month. Do these multiple payments hurt or help my credit score?

Answer: They probably help. The balance that matters for credit scoring purposes is the balance that’s reported to the credit bureaus, and that’s typically what you owe on your statement closing date. Making multiple payments before the statement closing date should lower that balance. Just remember to make a payment between the statement closing date and before the due date to avoid late fees.

Dear Liz: My mother has two credit cards that have had no activity for a year and a half due to being in an assisted living facility. She is living with dementia and no longer able to make any decisions (personal or financial) on her own. Should I or am I even able to cancel these cards or do I have to wait until she passes and send in a death certificate to the bank?

Answer: Theoretically you could close the accounts for her if you have a legal document known as a financial power of attorney. These documents are designed to help you take over the finances of someone who is incapacitated. Unfortunately, banks and credit card issuers sometimes refuse to honor powers of attorney despite legal requirements that they do so. You might need to hire an attorney to force them to accept your authority. You can get referrals to experienced attorneys from the National Academy of Elder Law Attorneys and the American Bar Assn.

If you don’t have this document and your mother is no longer of sound mind, you probably would have to go to court to become her conservator to make financial decisions for her. That can be an expensive process.

But there might be a simple solution. Some credit cards have an “off” switch that prevents anyone from making charges on the account. If the card has this feature and you can access the account online, you may be able to effectively disable the account even if you can’t formally close it.
