The Payment Card Industry Data Security Standard (PCI DSS) version 4.0 is the latest update to the globally recognised standard that outlines security requirements for organisations that handle credit and debit card transactions. As mobile payments become more prevalent, businesses must understand the requirements and best practices for complying with PCI DSS version 4.0.
Mobile payments have become increasingly popular in recent years, with consumers using their smartphones and other mobile devices to make in-store and online purchases. However, with this rise in mobile payments comes an increased risk of data breaches and other security threats. Businesses must comply with PCI DSS version 4.0 when accepting mobile payments.
Requirements for Mobile Payments under PCI DSS version 4.0
Under PCI DSS version 4.0, businesses that accept mobile payments must adhere to a set of requirements to ensure the security of sensitive cardholder data. Some of the critical requirements for mobile payments include the following:
Encryption: All cardholder data must be encrypted in transit and at rest. This means that any data transmitted between the mobile device and the payment gateway must be encrypted and stored on the mobile device itself.
Secure storage: If any cardholder data is stored on the mobile device, it must be stored securely. The data should be encrypted and protected by strong passwords or other access controls.
Access controls: Access to mobile payment applications or systems should be restricted to only authorised users. This can be achieved through strong passwords, two-factor authentication, or other security measures.
Security testing: Mobile payment applications and systems should undergo regular security testing to identify and address any vulnerabilities or weaknesses.
Compliance validation: Businesses that accept mobile payments must undergo regular compliance validation to ensure they meet all of the requirements of PCI DSS version 4.0.
Best Practices for Mobile Payments under PCI DSS version 4.0
In addition to the requirements outlined in PCI DSS version 4.0, businesses can follow several best practices further to enhance the security of their mobile payment systems. These include:
Use trusted vendors: Businesses should only use mobile payment vendors certified as PCI DSS compliant. This helps ensure that the vendor adheres to the highest security and data protection standards.
Keep software up-to-date: Mobile payment applications and systems should be updated regularly to ensure they are running the latest software version. This helps address any security vulnerabilities or bugs that may have been identified in previous versions.
Train employees: All mobile payment employees should receive regular training on securely handling and processing cardholder data. This can include training on password management, encryption, and access controls.
Implement firewalls: Mobile devices should have firewalls installed to protect against unauthorised access and prevent data breaches.
Monitor activity: Businesses should monitor mobile payment activity regularly to identify suspicious or unauthorised transactions. This can help to identify potential security breaches early on and prevent further damage.
