Visa requires merchants to submit the appropriate authorization reversal below within 24 hours of transaction completion:

• Partial authorization reversal. If the final transaction amount is lower than the amount initially authorized

• Full authorization reversal. If the purchase is cancelled or the transaction is not completed before the final amount is settled

To return cardholders' available funds as quickly as possible, the reversals must be submitted accurately and include all required data fields listed below:

• Visa Transaction Identifier (TID). For every message after an estimated authorization, this field must indicate the Visa-generated TID returned in the original authorization response. This links the estimated authorization request to all subsequent messages.

• Retrieval Reference Number (RRN). Must contain the RRN from the original authorization request message. It is used to identify and track all messages related to the transaction.

• Transaction Amount. The original transaction amount, or total authorized amount in the case of incremental authorizations.

• Replacement Amount. The corrected final amount of the authorized transaction.

Visa is enhancing their card-present $0 account verification (a “zero-dollar” check used to confirm a card is valid) to support PIN verification. This change aligns $0 verifications with standard purchase authorizations, so that the card’s bank can receive the PIN, verify it, and return in a PIN result.

On top of this, the enhancement helps support scenarios where you securely store a customer’s card for future merchant-initiated transactions, such as subscriptions or recurring payments.

What you need to do

If you use PIN with $0 account verification for Visa card-present transactions, please confirm that you are able to support:

1.    Receiving and handling PIN-related response codes returned on the $0 account verification response:

• 14 – Not in positive PIN verification file
• 55 – PIN incorrect or missing
• 75 – Allowable number of PIN-entry
• 81 – Cryptographic error found in PIN
• 86 – Cannot verify PIN (for example, no PVV)

2.    PIN retry behavior, including resending the $0 account verification when appropriate, following standard PIN retry logic.

If you are unsure whether you use $0 account verification PIN today, contact your JPMorganChase representative or your third-party processor/terminal provider for confirmation.

Visa strongly recommends that merchants include the Original Transaction ID (OTID) in all PAN- and token‑based standing instruction merchant‑initiated transaction (MIT) authorization. Merchants should:

• Always capture and pass the OTID in every MIT authorization message
• Ensure the initial cardholder-initiated transaction (CIT) includes the correct POS environment code with indicators I, R, or C, using the same credentials intended for future MITs
• Leverage Visa’s MIT Service to securely store, retrieve, and pass the OTID into the MIT authorization message to simplify implementation and ensure accurate linkage to the CIT 

Doing the above enables:

• Precise linkage from the initial CIT to follow‑on MITs at the subscription level, preventing over‑blocking and avoiding declines caused by merchant‑level stop instructions 
• Fewer repeated retries and declines, minimized compliance‑associated fees, and the ability to unlock more Visa value‑added services and insights through improved data integrity
• Merchant visibility into cardholder cancellation and subscription management via notifications

Effective April 17, 2026, Mastercard will reinstate the Fraudulent Processing of Transactions Chargeback as a compliance case.

This change addresses fraud schemes where customers are tricked into approving additional fraudulent, face-to-face, card-read transactions shortly after a legitimate purchase. These transactions can appear under a different merchant name or location.

A common fraud scheme works like this:

1. A cardholder tries to pay at the pump.

2. The attendant claims the transaction didn’t go through and brings the cardholder inside to pay (or offers to take the card inside for them).

3. Inside, the attendant uses a fraudulent or tampered merchant terminal to run an in-person, card-read transaction under a different merchant name and location than what the cardholder authorized.

As a result of this change, you may see an increase in dispute compliance cases related to above fraudulent activity scenarios.

Starting April 17, 2026, Mastercard will no longer allow full primary account numbers (FPAN) to appear in any document used for disputes. With this, merchants should NOT upload documents for Mastercard containing the FPAN, as this would violate Mastercard rules and may result in fines or additional fees. This rule also applies if the same document is sent again in a later¹ dispute and still shows the FPAN.

To avoid the violation, merchants should only show the last four digits of the card number in any document. Here are some ways to mask the rest of the numbers to ensure that the FPAN cannot be read or reconstructed:

• Cover the other digits with black ink
• Use a software to block out the digits
• Replace the digits with symbols like X, *, or #

Whatever method is used, make sure the FPAN cannot be read or reconstructed.

Mastercard has shared the following best practices for preventing enumeration attacks. These attacks involve fraudsters systematically testing card numbers and credentials to identify valid card details.

• Capture and validate CVC2. Always require and validate the CVC2 code when adding a card or processing transactions. This is mandatory for card add in the Europe region and strongly recommended elsewhere.
• Enable EMV 3-D Secure authentication. Ensure EMV 3-D Secure is performed for all card adds and e-commerce transactions to provide an additional layer of security and prevent unauthorized card use.
• Implement CAPTCHA technology. Use CAPTCHAs during card add and checkout to block bots and automated attacks.
• Use Address Verification Service (AVS). Where supported, use AVS to verify the cardholder’s address and further reduce fraud risk.
• Monitor for unusual activity. Watch for spikes in transaction declines, multiple card adds from the same IP address or account, and increases in high-dollar, cross-border transactions. Set up internal alerts for higher than usual failure rates in card adds and authorization transactions.
• Limit transaction velocity. Detect and prevent multiple card adds or transactions per user account or IP address within short time frames. Implement throttling to restrict the number of actions from a single user account or IP address.
• Meet PCI DSS Standards. Ensure your business and all third-party service providers (e.g., payment gateways and shopping cart providers) comply with PCI DSS requirements and have mechanisms to detect and prevent enumeration attacks.
• Report suspicious activity. Immediately report any suspected account takeover or enumeration attack to your bank.
• Remediation plan. Have a documented and actionable remediation plan to address enumeration attacks within 72 hours of detection or notification by your bank or Mastercard.

Implementing these measures will help reduce fraud losses, protect cardholder data, and maintain trust with your customers. Please review your current processes and update them as necessary to comply with Mastercard’s recommendations.

They must also include the original PAN and expiration date, a tokenized-stored credential obtained through Secure Remote Commerce tokenization, or new account information from the cardholder or Automatic Billing Updater.
• Token cryptogram exception. If token cryptogram data is used in a declined merchant-initiated transaction (MIT) authorization request, it must not be reused in subsequent resubmissions.
• CNP transaction restrictions. Declined card-not-present (CNP) cardholder-initiated transactions must not be resubmitted as an MIT, except for transit debt recovery.
• Merchant advice codes. Merchants should use the decline reason and merchant advice code from the issuer's response in their resubmission strategies for MITs.
• Prohibition of data manipulation. Merchants must not manipulate transaction data in resubmissions to evade payment arrangement cancellations. This includes altering the acceptor ID or acceptor name used in the merchant's transaction messages, or shifting the merchant's transaction volume to a different acceptor ID.
• Response code restrictions. If any of the following response codes are received in the issuer’s authorization response for a merchant-initiated CNP transaction, do not make additional authorization requests for the same transaction with the same account information (PAN and expiration date combination) at any time:
  • 04 (Capture card)
  • 14 (Invalid card number)
  • 15 (Invalid issuer)
  • 41 (Lost card)
  • 43 (Stolen card)
  • 54 (Expired card)

Starting January 1, 2026, Discover will require all cards to be compliant with D-Payment Application Specification (D-PAS) Connect. Ensure that your contactless D-PAS terminals have the correct terminal transaction qualifier (TTQ) to avoid terminated transactions. Discover will also discontinue support for offline plaintext PIN (OPTP).

In addition, by December 31, 2025, contactless terminals must cease supporting Zip or CTL-MSD transactions and be updated to support EMV contactless payments. D-PAS Connect transactions will fail if terminals only support CTL-MSD or Zip.

Please visit our Developer Center for the full D-PAS details. If your POS is managed by a third-party provider, please contact them to ensure compliance.

Update: Starting March 21, 2026, Accel and STAR fraud chargebacks will be challenged through the Outgoing Pre-Arbitration Cycle, where:

• Status updates will be visible in the Chargeback Management (CBIS) user interface
• Funds will only be transferred if the card issuer accepts the chargeback or does not respond within the required timeframe

On March 21, 2026, Fiserv will migrate the exception processing platform for Accel and STAR to Transaction Research and Exception Processing (TREP). This will lead to a revision in Accel’s timeframe for merchant response to chargebacks/exceptions, while STAR’s will remain unchanged, as shown in the table below. Exception items created before the update will adhere to the current timeframes.
