If someone uses a stolen credit card and they are caught and convicted they can get 1 year in jail or up to 15 to 20 years in prison.
That depends on how much money they stole when using the stolen credit card and if they have other criminal records.
If someone steals your credit card or you lost your credit card you need to contact the credit card company immediately and let them know about it.
You should also contact the police department and report it as lost or stolen just in case someone does use your credit card.
That would mean they would have that on file in case someone does use it.
If you contact your credit card company immediately then you won't be liable for charges to your credit card that someone else does.
