I have gas station car wash & c-store, been on both sides of the stick. As an employer I post signage CC fraud 1st offense 3 years in jail. Your debt card if it’s a visa master etc...can be used as a regular CC. so no pin is needed, easy for any employee to get. If you have a bank debt card make sure you have a good pin, don’t use home address, phone #, name etc... If I have John Smiths CC # I go online and I can get any personnel info needed to try pin's. Once my wife lost her wallet on vacation, sitting at burger king my 12 year old son wanted to get another burger he grabbed wallet from her purse took $2. out and left it on seat. Needless to say it was a nightmare SS #’s License, CC etc… and we’re 2000 miles from home. Since most of our CC are same accounts we were able to cancel some of them but not all. Could not figure out who to call and how to cancel others. Now we keep a separate ledger of CC in a safe place to access (with her dad at home or one of my brothers). The best thing about CC is stay in good standing and good credit 99% of the time your CC company will stand behind you. Even as a business I had a guy getting gas 2 times a week would often challenge a charge, I get notified 2 months later to produce a signature in 10 days. I get billed $25. for the challenge and if I can produce the signature I will get the reimbursement (but not the $25.) If I miss the 10 days (have to go through boxes of CC receipts) The guy rips me off for a $40.00 gas and I get charged $25.00. When you only make .10-.12 per gal. that sucks.
