Carl Mahoney owns a ladies' perfume shop. At the start of his business, he used his garage and converted it into a makeshift store where customers can drop by and purchase items using cash, credit cards or personal checks.

Nowadays, credit cards are no longer secure. It can be tampered or even faked. Anyone with general knowledge about computers can intercept and “ steal” credit card information sent over the Net. It takes only some tinkering and it's done.
