Even though business planning, bookkeeping & administration are important for business success, the most important aspect of any business is sales & marketing. Operations, administration, strategic planning & bookkeeping are all necessary but irrelevant without the generation of leads & new customers.
Where to Locate your Security Code. Debit card security codes are located on the back of the card. The last three numbers to the right of the card are known as your security code. Why the Security Code is Important. The security code offers the cardholder an extra layer of protection from fraud and unauthorized use.
Where you find the security code depends on the card. If you have a Visa, MasterCard or Discover, turn the card over. In the signature box or just to the right of it, you will see a series of digits. However long the series, the final three digits are the security code. American Express cardholders can find their security code on the front of the card, either to the left or right of the embossed 15-digit card number. These four digits are printed in black, not embossed.
