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.

Tompkins County Public Library (TCPL) complies with all PCI standards regarding the storage, processing and transmission of customer credit card information for payment of fines and fees, and meeting room rentals that we process through our Circulation Desk.  Finger Lakes Library System is PCI DSS compliant for patrons who make account payments on the TCPL website.  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.

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 TCPL service desks at Circulation, Information and Learning Services, and Youth Services


  1. This policy applies to all Library employees and to contractors and consultants who have access to cardholder data.
  2. 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.
  3. The Library uses a POS terminal not connected to the Internet. It uses a dedicated phone line for transactions.
  4. 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.
  5. No cardholder data shall be entered or stored under any circumstance. This includes:
    • The card verification code or value (three-digit or four-digit number printed on the front or back of a payment card).
    • The personal identification number (PIN) or the encrypted PIN block.
  6. Cardholder data may not be transmitted via email.
  7. 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.
  8. All Circulation Clerks are issued a clerk number that is recorded with the Head of Access and Circulation 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.
  9. 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 and Circulation Services should be notified immediately of any suspected or real security incidents involving cardholder data:

  1. Contact the Access and Circulation Services Department Head (ACS DH) who will contact the Business Manager to report any suspected or actual incidents. Staff should contact the ACS DH if it occurs during non-business hours.
  2. Document any information you know while waiting for the ACS DH 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.
  3. 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.

Incident Response Policy (Handled by ACS DH and Business Manager)

Responses can include or proceed through the following stages: identification, severity classification, containment, eradication, and recovery resulting in improvement of security controls.

Contain, Eradicate, and Recover

  1. Notify applicable card associations.
    • Visa
      Provide the compromised Visa accounts to Visa Fraud Control Group within ten (10) business days. For assistance, contact 1-(650)-432-2978. Account numbers must be securely sent to Visa as instructed by the Visa Fraud Control Group. It is critical that all potentially compromised accounts are provided. Visa will distribute the compromised Visa account numbers to issuers and ensure the confidentiality of entity and non-public information. See Visa's "What to do if compromised" documentation for additional activities that must be performed. That documentation can be found at
    • MasterCard
      Contact your merchant bank for specific details on what to do following a compromise. Details on the merchant bank (aka. the acquirer) can be found in the Merchant Manual at
    • Discover Card
      Contact your relationship manager or call the support line at 1-(800)-347-3083 for further guidance.
  2. Alert all necessary parties. Be sure to notify:
    • Merchant bank
    • Local FBI Office
    • U.S. Secret Service (if Visa payment data is compromised)
    • Local authorities (if appropriate)
  3. Collect and protect information associated with the intrusion.
  4. Eliminate the intruder's means of access and any related vulnerabilities.
  5. Research potential risks related to or damage caused by intrusion method used.

Payment Location: Payments handled at the public print release station

Jamex supplies TCPL with the device that accepts credit card payments at the print release station. According to their document titled, "NetPad Touch for Credit Card End to End Encryption E2EE,"

NetPad Touch for Credit Card has been implemented to provide maximum PCI security. By partnering with CreditCall, a global payments company with offices in North America and Europe, the NetPad provides state of the art encryption from card swipe through completion of transaction.”

CreditCall is a validated PCI DSS Level 1 Service Provider. This is the industry’s highest level of certification. Reviewed annually, an intensive onsite audit ensures the highest compliance levels are maintained and adhered to. To comply with the strictest security measures, CreditCall does not store raw magnetic stripe (track 2), card validation codes or PIN block data.

The NetPad touch uses an encrypted card reader that can only be decrypted by CreditCall. 

All communications from the NetPad Touch are outbound over HTTPS to the CreditCall server. The use of an encrypted reader in conjunction with direct communication only to the CreditCall server provides a PCI DSS compliant solution.

Please contact the Business Manager at the Tompkins County Public Library if you would like a copy of the complete document.

Payment Location: Payments made through online catalog for fines and fees

The Finger Lakes Library System maintains TCPL's online catalog and handles online payments made through it. Below is the Finger Lakes Library System Privacy Policy for Credit Card Transactions:

All credit card transactions are conducted on the PayPal PayFlowLink gateway hosted pages ensuring Payment Card Industry (PCI) compliance standards. We use a 2048 bit SSL Certificate from a recognized Certificate Authority (CA) for all public facing pages where personally identifiable information (PII) is stored. Since all credit card transactions occur on the PayFlowLink hosted pages, we don't have access to or store any credit card numbers. The lock icon indicates that your browser is communicating over a secure link.

Refunds will not be issued via the online credit card web page. Overdue fines can only be refunded by the library (check or cash) where the fine was incurred. Any returned items that were Lost and then Paid must seek the refund from the Library that owns the item. The period of time that a Library may issue a Refund is governed by the owning library only. This period ranges from 1 month to 1 year depending on the owning library policy.

Payment Location: Donations made to the Tompkins County Public Library Foundation

Tompkins County Public Library Foundation uses a third-party vendor called Blackbaud to take online payments. Blackbaud is PCI compliant and their statement can be found at

Payments mailed to the Foundation office are retained in a secure area and follow the Federal Record Retention Requirements. After this time, the receipts are sent to a professional shredding service to be destroyed.
