  • Location: Specify the physical location where the POI device is deployed (e.g., store address, department).
  • Unique Identifier: Include a unique identifier for each device, such as the serial number or another assigned ID.

Business implication

• Enhanced Detection of Missing Devices: An accurate POI device inventory allows you to track all devices and quickly identify any missing equipment. This helps detect potential security incidents like device theft or unauthorized removal, which could lead to card data breaches.

Best practices to meet this requirement

• Develop POI Device Inventory System: Establish a system for tracking all POI devices within your environment. This could be a dedicated software tool, a spreadsheet, or a physical inventory log.
• Inventory Update Procedures: Define procedures for updating the POI device inventory whenever there are changes (adding new devices, relocating existing ones, decommissioning old devices).
• Regular Inventory Reconciliation: Periodically reconcile your physical inventory of POI devices with the documented list to ensure accuracy.

How to comply with this PCI DSS requirement

PCI DSS Requirement 9.5.1.2: Periodic inspections of POI device surfaces

This requirement focuses on conducting regular inspections of Point-of-Interaction (POI) device surfaces to detect signs of tampering or unauthorized substitution. POI devices are those used for capturing payment card data through physical interaction with the card (swiping, dipping, tapping).

• POI Device Inspections: The requirement mandates regular visual inspections of POI devices to identify any physical alterations or indications that the device might have been tampered with or replaced with a fraudulent one.

Business implication

• Early Detection of Skimming Devices: Regular inspections of POI devices help identify skimming attachments or fraudulent devices before they can be used to capture cardholder data. This minimizes the potential financial losses from fraudulent transactions and the reputational damage associated with a data breach.

Best practices to meet this requirement

• Develop POI Device Inspection Procedures: Establish documented procedures outlining the process for conducting periodic inspections of POI devices. These procedures should specify the frequency of inspections, what to look for during inspections, and who is responsible for conducting them.
• Inspection Training: Train personnel responsible for inspecting POI devices on how to identify potential signs of tampering, such as unusual attachments, changes in device appearance, or damaged security labels.
• Inspection Checklists: Develop checklists to guide inspectors during their examination of POI devices. These checklists should list specific areas to examine and potential signs of tampering.
• Documentation of Inspections: Maintain records of completed POI device inspections, including the date, inspector name, any observations made, and any corrective actions taken.

PCI DSS Requirement 9.5.1.3: Training for personnel in POI environments

This requirement focuses on providing training to personnel who work in Point-of-Interaction (POI) environments to ensure they are aware of potential tampering attempts and understand procedures for protecting POI devices. POI devices are those used for capturing payment card data through physical interaction with the card (swiping, dipping, tapping).

• POI Environment Personnel: This applies to any employee who works in an area where POI devices are located, including cashiers, sales associates, and maintenance staff.
• Security Awareness Training: The requirement mandates training that covers specific areas related to POI device security:
  • Verifying Third-Party Personnel: Employees should be trained on how to verify the identity of anyone claiming to be maintenance or repair personnel before granting them access to POI devices. This includes verifying work orders and contacting the authorized maintenance company for confirmation.
  • Device Verification Procedures: Personnel should understand procedures for ensuring proper installation, replacement, or return of POI devices. This may involve verifying device details against an inventory list before deployment.
  • Suspicious Activity Awareness: Employees need to be trained to identify suspicious behavior around POI devices, such as unauthorized individuals tampering with devices or attempting to unplug them.
  • Reporting Procedures: Personnel should be aware of established procedures for reporting any suspicious activity or indications of device tampering or substitution. This may involve reporting to a manager, security officer, or designated contact.

Business implication

• Reduced Risk of Social Engineering Attacks: Training employees to be vigilant and identify suspicious behavior around POI devices helps prevent criminals from posing as authorized personnel to gain access and tamper with devices. This minimizes the risk of card data breaches and associated financial losses.

Best practices to meet this requirement

• Develop POI Security Awareness Program: Establish a formal training program to educate personnel in POI environments about protecting these devices.
• Training Content: Include all elements specified in the requirement within your training program.
• Verification Procedures: Clearly define procedures for verifying the identity of third-party personnel and verifying devices before installation, replacement, or return.
• Suspicious Activity Guidance: Provide clear examples of suspicious behavior around POI devices to help employees identify potential threats.
• Reporting Channels: Establish clear communication channels for employees to report suspicious activity or concerns about POI device tampering.
