In 2002 the State prohibited business from printing the full credit card numbers on receipts. Now the State is seeking to extend that prohibition to the use of debit cards. Senate 849 would prohibit business owners from anything other than the last 5 digits of a debit or credit card on a receipt or other document. There is an exception for business that record the credit card number by hand or use the imprint machines.
I would suspect that most credit card machines do this automatically so hopefully this bill will have little impact on the daily runnings of your business.
