From fraud prevention tips to innovative security technologies, we provide powerful resources to help keep your business safe and secure.
Security training
Visa provides valuable information regarding the latest data security trends, data breaches and attack vectors, best practices and Visa compliance programmes through an on-going series of conferences, webinars and training sessions.
PCI DSS compliance
Everyone storing, processing or transmitting cardholder information is required to follow the PCI DSS. It consists of 12 basic requirements grouped in 6 categories for establishing and maintaining a reliable and secure payment processing environment. Partner with your acquirer to provide secure transactions for all customers using the PCI Data Security Standard (DSS). First, review the guidelines and then check to see that you meet the related requirements.

Compliance validation
Take the time to see that you’ve met all requirements of the PCI DSS. It’s the best way to confirm cardholder data is being safely handled and to expose any weaknesses that need to be addressed. Your total Visa transaction volume over a 12-month period determines your merchant level and the necessary requirements for validation.

Technology Innovation Programme
Invest in secure technology and make compliance easier
US merchants that have acted to help prevent counterfeit fraud by investing in EMV chip technology or implemented a validated point-to-point encryption solution can benefit from Visa's Technology Innovation Programme (TIP). This programme rewards eligible merchants by eliminating the requirement to verify compliance with the PCI DSS when at least 75 per cent of yearly transactions originate from dual-interface EMV chip-enabled terminals or a validated point-to-point encryption solution.
Regulations + assessments
Visa Core Rules (VCR) governs the activities of client financial institutions and, by extension, merchants and service providers as participants in the Visa payment system.
A merchant's acquiring bank is responsible for ensuring the PCI Data Security Standard (DSS) compliance of the merchant and any service providers the merchant is using. As a merchant, you must maintain full compliance at all times. (VCR section ID #0002228 and #0008031).
If a merchant does not comply with the PCI DSS or fails to rectify a security issue, Visa may assess a non-compliance assessment to the merchant’s acquirer. The acquirer is responsible for paying all assessments and must not represent that Visa has imposed any assessment on the merchant. (VCR section ID #0001054)
Assessments may be waived if there is no evidence of PCI DSS non-compliance prior to, and at the time of a data breach, as demonstrated during a forensic investigation.
Service providers + payment applications
Support secure transactions by partnering only with approved service providers and payment applications.
Service providers
