Payment Card Industry Data Security Standard (PCI DSS) Compliance Policy

Payment Card Industry Data Security Standard (PCI DSS) Compliance Policy

Payment Card Industry Data Security Standard (PCI DSS) compliance are security and business practice guidelines adopted by Visa, MasterCard, American Express, Discover Card, and JCB to establish a “minimum security standard” to protect customer’s payment card information. It is a requirement for all merchants that store, transmit, or process payment card information.

The Tompkins County Public Library (TCPL) complies with all PCI standards regarding the storage, processing and transmission of customer credit card information for payment that we process through our Circulation Desk.  The Finger Lakes Library System is PCI DSS compliant for patrons who make account payments on the TCPL website.  The Tompkins County Public Library Foundation uses a service that is PCI DSS compliant for patrons that make online donations on the Foundation’s website.



Cardholder Data: At a minimum, cardholder data consists of the full primary account number (PAN). Cardholder data may also appear in the form of the full PAN plus any of the following: cardholder name, expiration date and/or service code.

Information Security: Protection of information to insure confidentiality, integrity, and availability.

PAN: Acronym for “primary account number” (or “account number”). This is a unique payment card number (typically for credit or debit cards) that identifies the issuer and PCI: Acronym for “Payment Card Industry.”

POS: Acronym for “Point of Sale.”

Terminal: The device used to manually process the credit cards.


Payment Location: Payments handled at the TCPL service desks at Circulation, Adult Services, and Youth Services


a. This policy applies to all Library employees and to contractors and consultants who have access to cardholder data.

b. All employees who have access to cardholder data must attend security awareness training and acknowledge in writing that they have read and understand the Library’s Information Security Policy. This policy will be reviewed with applicable staff annually.

c. The Library uses a POS terminal not connected to the Internet. It uses a dedicated phone line for transactions.

d. The Library accepts payments via telephone.  The telephone is within close proximity to the credit card terminal so there is usually no need to write down card information because it can be entered directly into the terminal.  If a staff person from another department writes down credit card information to enter into the terminal, they immediately shred the information once the transaction is finished.

e. No cardholder data shall be entered or stored under any circumstance.  This includes:

  • i. The card verification code or value (three-digit or four-digit number printed on the front or back of a payment card).
  • ii. The personal identification number (PIN) or the encrypted PIN block
  • iii. The contents of the payment card magnetic stripe (track data) on any media whatsoever. 

 f. Cardholder data may not be transmitted via email.

g. No more than the last four digits of a PAN shall be printed on either the Library copy or the customer copy of any receipts or reports.

h. All Circulation Clerks are issued a clerk number that is recorded with the Head of Access Services.  Clerks must include their clerk number when entering their transaction into the register.  This number is also written on the credit card slip before it is placed in the register drawer.

i. Credit card receipt copies are sent to the Business Office and retained following the Federal Record Retention Requirements.  After this time, the receipts are sent to a professional shredding service to be destroyed.


Reporting an Incident

The Head of Access Services should be notified immediately of any suspected or real security incidents involving cardholder data:

a. Contact the Head of Access Services (HAS) who will contact the Business Manager to report any suspected or actual incidents. Staff should contact the HAS if it occurs during non-business hours.

b. Document any information you know while waiting for the HAS to respond to the incident. If known, this must include date, time, and the nature of the incident. Any information you can provide will aid in responding in an appropriate manner.

c. No one should communicate with anyone outside of their supervisor(s) or the Business Manager about any details or generalities surrounding any suspected or actual incident.  All communications with law enforcement or the public will be coordinated by the Business Manager.
