9 Payment Card Industry Data Security Standard – PCI DSS What is PCI Compliance? The PCI Data Security Standard represents a common set of industry tools and measurements to help ensure the safe handling of sensitive information. Initially created by aligning Visa's Account Information Security (AIS)/Cardholder Information Security (CISP) programs with MasterCard's Site Data Protection (SDP) program, the standard provides an actionable framework for developing a robust account data security process - including preventing, detecting and reacting to security incidents.For more information about PCI DSS visit

17 For more information about PCI DSS visit www.pcisecuritystandards.org What do I need to do?PROTECT CARDHOLDER DATA!!!Every department that accepts credit card payments needs to evaluate their current credit card process and verify that they are doing everything possible to ensure the security of cardholder data.Two truths about PCI ComplianceIt is very possible that your costs for card acceptance will go up.You may have to change the way you process payment cards.For more information about PCI DSS visit
18 What information needs to be protected? Not all information related to a credit card transaction need to be protected.There is cardholder data and payment data.Payment data should be kept for auditing purposes.Cardholder data should not be stored.
19 Cardholder Data vs Payment Data Payment data includesCardholder nameTransaction dateLast 4 Digits of credit card numberAuthorization codeCard typeAmountThis information should be stored for 3 years per the record retention schedule.
20 Cardholder Data vs Payment Data Cardholder Data – Should NOT be stored.
21 CVV2 – 3 or 4 digit codeNEVER store CVV2 data (3 or 4 digit code found on the back of a card)If you have this stored somewhere – DESTROY IT.If it is stored in old records, you need to go back and DESTORY IT.In the event of a compromise, if you have this information, the severity of the compromise greatly increases.*If your terminal asks for this code and you would rather not be responsible for it, let me know and we can have your terminal reprogrammed to not ask for this code.
22 Cardholder Data vs Payment Data Cardholder data – You do not need it, SO DON’T STORE IT.Misconception - I need to keep the credit card number.Process refund – There are other ways to do this.Ask the cardholder for their card number.You can get the credit card number off of the processorsonline reporting website.If you are using an approved service providers website, you do not need to cardholder data to process a refund.You can call the processors helpdesk for assistance.Any other reasons you need cardholder data?*Think about whether the storage of cardholder data and the business purpose it supports are worth the risk of having data compromised.
23 Cardholder DataTake inventory of all the places you store cardholder data and destroy it especially if you have the CVV2 (3 or 4 digit code).*Exception – Terminal Merchants: if the full 16 digit card number is printed on the merchant receipts, you are allowed to store these in a secure location because the payment data is also included. FYI…We will be changing all CMU terminals to only print the last 4 digits in the next 2 months.
