Yes, you can give your credit card to someone else to use, even if they are not an “authorized user” with the credit card company, and whether or not they are a relative. Be aware, your credit card agreement states that any charges made by another person with your permission are entirely your responsibility to pay.
Can someone use my credit card with authorization?
Temporary Use In some cases, you can give someone, such as a relative or friend, authorization to use your credit card account. You may also have to write a signed note authorizing the person. Also, allowing someone else to sign for transactions on your credit card could go against your credit card service agreement.
How long is an authorization good for on a credit card?
between 1-30 days

When is it considered forgery when you are given consent to?
Usually not, but it can be. If you are just signing a document on someone else’s behalf with their permission, it is not forgery. But if you are misrepresenting yourself as them, like taking a drug test for them, it can be. Originally Answered: Is it considered forgery when you are given a consent to copy one’s (their) signature?
Can a son sign his father’s name on a credit card purchase?
Signing another’s name can put you on shaky legal ground. Without proper legal documentation, such as a power of attorney, signing your father’s name is forgery and a clear violation of the father’s credit card agreement. However, if the father has given permission and willing to pay the charge on the card, the son may be able to sign.
Is it forgery to copy someone else’s signature?
No; the term “forgery” almost always is based on the fraudlent reproduction of another’s signature. If you have permission, you are not doing so with the intent to defraud, so it is not “forgery” — legally speaking, you’re acting as the agent of the signatory.
Is it illegal to forge someone’s signature on a contract?
It could complicate whatever agreement someone is entering into, however, and there are cases where it is illegal. A contract isn’t a piece of paper, and a signature doesn’t make it binding. A contract exists when there is an agreement, the paper and signature are just evidence of what was agreed to, in case there is a dispute.
