Is it illegal to charge a debit card fee in Texas?

Could you please clarify for me if it's against the law in the state of Texas to impose a fee on customers who choose to pay using a debit card? I'm trying to understand the regulations surrounding payment processing and want to ensure that my business practices comply with all applicable laws. I'm particularly interested in knowing if there are any specific restrictions or guidelines that govern debit card fees in Texas. Thank you for your help in clarifying this matter.
