You can legally let someone else use your credit card, but almost every cardholder agreement forbids it, and if you do it anyway you remain personally responsible for every charge with no fraud protection to fall back on. The safer route, if you want another person to make purchases on your account, is to add them as an authorized user through your card issuer.
Your Cardholder Agreement Says No
A credit card is a contract between you and the issuing bank. Nearly all of those contracts state that the card is non-transferable and may only be used by the named cardholder or an approved authorized user. Handing your card to a friend, roommate, or adult child without going through the bank’s process breaks that agreement.
Banks run automated risk systems that flag unusual spending — a purchase in a new city, a category you never use, a sudden spike in activity. If the issuer decides someone other than you is using the card, it can freeze or permanently close the account. A closed account can hurt your credit score by cutting your total available credit and shortening your credit history, and you may lose any rewards or points you had built up.
You Owe Every Charge They Make
As the primary cardholder, you owe the full balance regardless of who physically swiped or tapped the card. There is no mechanism through the bank to shift that responsibility to the person you lent it to. If a friend charges $3,000 and refuses to pay you back, the issuer looks to you. Unpaid balances collect interest, trigger late fees, and can be sent to collections or turned into a lawsuit against you.
A boundary worth knowing: if you let someone charge significant expenses on your card and never seek repayment, the IRS could treat those payments as gifts. For 2026, the annual gift tax exclusion is $19,000 per recipient; amounts above that require a gift tax return, though no tax is owed until you exceed the lifetime exemption.1Internal Revenue Service.

The $50 Fraud Cap Won’t Save You
Many people assume the $50 liability cap on fraudulent credit card charges will protect them if things go wrong. It won’t. That cap, from the Fair Credit Billing Act, applies only to “unauthorized use,” and federal law defines that narrowly: a transaction by someone who does not have “actual, implied, or apparent authority” from the cardholder and from which the cardholder receives no benefit.2Office of the Law Revision Counsel. 15 USC 1602 – Definitions and Rules of Construction
When you voluntarily hand over your card, you give the other person actual authority to use it. Any charges they make are therefore authorized under federal law, even if they spend more than you expected or buy things you didn’t approve. The $50 cap in 15 USC 1643 never kicks in, and you’re on the hook for the full amount.3Office of the Law Revision Counsel. 15 USC 1643 – Liability of Holder of Credit Card Filing a fraud dispute in this situation can itself create legal problems, since you did give permission for the card to be used.
Trouble at the Register
Lending your card isn’t a crime, but complications can hit the person carrying it. Merchants are expected under their payment-network agreements to verify that the person presenting the card is the authorized cardholder. If the name on the card doesn’t match the buyer’s ID, a cashier or manager may suspect the card is stolen. That can lead to a refused sale, a call to the police, or the borrower being questioned.
Federal law makes it a crime to use a credit card obtained through fraud, theft, or forgery in a transaction affecting interstate commerce. Penalties include fines up to $10,000, up to ten years’ imprisonment, or both.4Office of the Law Revision Counsel. 15 USC 1644 – Fraudulent Use of Credit Cards; Penalties The statute targets people who use cards without the owner’s consent, but the borrower may have to prove they had permission, which is stressful even when no charges are filed. State fraud and identity-theft laws add another layer.
Network rules vary on ID checks. Visa’s rules generally allow merchants to ask for identification but not to require it as a condition of accepting the card, except in certain fraud-control situations.5Visa. Visa Rules and Policy In practice, plenty of retailers do check IDs on higher-value purchases and will decline the sale if the names don’t match.
Add Them as an Authorized User Instead
If you want another person to make purchases on your account, the correct route is to add them as an authorized user. The bank issues a separate card in their name. They can use it at any register without tripping fraud alerts or getting turned away, and the arrangement is transparent to the bank, the payment network, and the merchant. You still owe every charge, but you also keep control: you can remove the authorized user at any time by calling customer service, and the change usually takes effect immediately.6Consumer Financial Protection Bureau.

An authorized user is not the same as a joint account holder. A joint holder shares equal legal responsibility for the balance and can’t be removed without closing the account. Most major issuers no longer offer joint accounts to new applicants, so authorized-user status is the standard way to share card access.
What the Issuer Will Ask For
What each issuer requires varies, but common data points include:
- Full legal name — required by all issuers
- Date of birth — required by all issuers
- Social Security number — required by some issuers but not all; Capital One, Chase, Citi, and Barclays let you add an authorized user without one, though providing it enables the account to be reported to credit bureaus
- Current address, for card delivery
- Relationship to the cardholder, requested by some issuers such as Chase and Barclays
You can usually submit the request through your online account dashboard, your mobile app, or by calling the number on the back of the card. Approval typically takes one to two business days, and the physical card arrives by mail within 7 to 10 business days. American Express, Chase, and Capital One offer instant access to the card number through their apps, so the authorized user can load it into a digital wallet and start using it before the plastic shows up.
Setting Spending Limits
One drawback of authorized-user status is that the person can, by default, access your full credit line. A few issuers address this directly. American Express offers spending limits on all of its consumer cards, with minimums as low as $200. Citi offers this on its Costco Anywhere Visa card. Barclays takes a different approach, letting you block individual authorized-user transactions above a chosen amount rather than capping total spending. If your issuer doesn’t offer any of this, you’re left with monitoring the account and setting expectations directly with the user.
Effect on the Authorized User’s Credit
Card issuers typically report authorized-user accounts to the major credit bureaus, so the account’s payment history, balance, and credit limit show up on the authorized user’s credit report. If you pay on time and keep the balance low, it helps them. If the account carries late payments or high utilization, it hurts them. Current FICO scoring models give authorized-user accounts less weight than accounts where the person is the primary borrower, so this is a useful tool for someone building credit from scratch but not a replacement for an account in their own name.
If You Need to Cut Them Off
Call the issuer and ask to remove the authorized user. The change usually takes effect right away, and their card stops working.6Consumer Financial Protection Bureau. How Do I Remove an Authorized User From My Credit Card Account? Ask whether you should also get a new card number: if the former user has your number memorized or saved in an online store, a new number keeps them from continuing to charge. You’ll still owe anything that posted before the removal went through.
