What your daughter did was illegal, and probably constituted Credit Card Fraud. In the state of Texas, this is a state jail felony that carries from 6 months to 2 years in state jail or up to 5 years of probation and a fine of up to $10,000.
The question you have to ask yourself is whether or not you should report this to the police. If she is convicted, your daughter will be a convicted felon for the rest of her life. A final conviction for theft never drops off your record and can prevent her from getting a job, renting an apartment, buying a house, etc. You need to consider those consequences before reporting this to the police and the credit card company.
