New options for merchants in the U.S. & Canada From 14 April 2018, EMV-enabled merchants in the U.S. and Canada have the option to stop capturing signatures as a method of cardholder verification. Those same merchants will also no longer be required to retain and store transaction receipts.
As the payment system has evolved, instances in which a transaction is initiated with a stored credential based on a cardholder’s consent for future use have increased to significant levels. To help merchants and acquirers understand the Stored Credential and Merchant Initiated Transaction framework, Visa is summarizing the requirements and implications through this supplemental document. Please refer to October 2016 VisaNet Business Enhancement Global Technical Letter and Implementation Guide for full details.

Today, cardholders have real-time, 24/7 access to their online banking through smartphone and other device apps. Purchase information is quickly updated to a cardholder’s account, however, a similar flow of information does not exist on purchase returns. Visa’s new return authorization messages will enable issuers to update cardholders’ online banking statements in real time and provide text alerts to those cardholders that opt in to the service with their issuer. This new service will improve customer experience, reduce inquiries related to lack of real-time information, provide real-time issuer account validation, and minimize related chargebacks.

Visa has been working with merchants, acquirers, and fuel-industry providers to support migration to the more secure EMV technology. The EMV liability shift is designed to better protect all parties. With the new rules, the party that is the cause of a chip transaction not occurring, either the issuer or acquirer, will be held financially responsible for any resulting card-present counterfeit fraud losses. However, due to challenges with EMV Automated Fuel Dispensers (AFD) solution readiness, Visa is delaying the U.S. domestic AFD EMV liability shift date to 1 October 2020.

As the US market migrates to EMV chip, the fraud threat from criminals placing skimming devices on, or in, attended and unattended point-of–sale (POS) devices for the purpose of collecting payment card information, including PIN numbers, increases. Perpetrators use skimmed payment information to quickly create counterfeit cards re-encoded with the stolen card information typically resulting in ATM withdrawals. To help clients combat skimming, Visa is providing guidance on recommended inspection and response actions. This data security alert may be disseminated to all payment system stakeholders.
Chip card technology in the U.S. has created new challenges for committing fraud at the physical point of sale.

This document provides guidance for issuers that plan to develop or use a third-party dynamic Cardholder Verification Method (CVM) service to authenticate their cardholders. Dynamic CVMs, such as One-Time Passcodes (OTP), are becoming more prevalent for on-line banking and e-commerce transactions as financial institutions aim to strengthen their customer authentication capabilities. Visa developed the following dynamic CVM best practices for issuers to consider and assess the security features of these solutions.

Visa shares best practices to help defend against poor implementation, maintenance and support processes that have led to merchant and agent data compromises. Visa advises acquirers, merchants, agents and payment application vendors to contact their licensed integrators and resellers, and insist that these best practices be immediately adopted. Merchants and agents should also consider including these best practices as a condition of their service level agreements with third party integrators and resellers.
Recent payment card data compromises have demonstrated the critical need for payment application companies to maintain mature software processes for their customers that go beyond Payment Application Data Security Standard (PA-DSS) compliant software. Acquirers, merchants and agents should review Visa’s best practices and insist that their payment application vendors, integrators and resellers fully adopt these practices
In October 2009, Visa published the Visa Best Practices for Data Field Encryption to promote the proper encryption of sensitive card data that is transmitted, processed or stored by stakeholders throughout the payment system. As part of these best practices, Visa recommended that entities use tokens (such as a transaction ID or a surrogate value) to replace the Primary Account Number (PAN) for use in payment-related and ancillary business functions. Tokenization can be implemented in isolation or in concert with data field encryption to help merchants eliminate the need to store sensitive cardholder data after authorization. Entities that properly implement and execute a tokenization process to support their payment functions may be able to reduce the scope, risks and costs associated with ongoing compliance with the Payment Card Industry Data Security Standards (PCI DSS).
To reinforce its commitment to protecting consumers, merchants, and the overall payment system, Visa is pursuing a global security objective that will enable merchants to eliminate the storage of full PAN and expiration date information from their payment systems when not needed for specific business reasons. To ensure consistency in PAN truncation methods, Visa has developed a list of best practices to be used until any new global rules go into effect.
Corporate Franchise Servicer entities operate in a number of merchant segments, including lodging and food service. In an effort to address the increasing threat of data compromises that affect franchise businesses, effective immediately, Visa will extend the Third Party Agent Program to include a new category of agents, called “Corporate Franchise Servicers.” Corporate Franchise Servicers (CFS) operates in a number of merchant segments, including food service and lodging. The inclusion of Corporate Franchise Servicer agents in the Visa Third Party Agent Program will help ensure that Corporate Franchise Servicer agents protect card data by at a minimum complying with the Payment Card Industry Data Security Standards (PCI DSS).
It is common practice for some card issuers to print the full PAN on each page of a cardholder’s billing statement; however, Visa strongly recommends that, as a “best practice,” issuers truncate or eliminate the printing of the cardholder PAN on billing statements and other cardholder communications.
Visa Operating Regulations specify that all Visa clients, including issuers and acquirer financial institutions, must comply with the Payment Card Industry Data Security Standard (PCI DSS). This bulletin specifies the requirements and recommendations necessary for facilitating this compliance.
