EMV Settings

EMV configuration is a set of rules, security keys, and card-brand parameters that allow the device to process chip-card transactions securely.

EMV Inside and Outside

EMV is configured Inside and Outside.

EMV AID Configuration

AIDs tell the Verifone Commander which EMV applications it can use to process chip cards. Each AID matches a card brand or network, ensuring the terminal follows the right rules and security steps. Without the correct AIDs, some chip cards may not process correctly.

AID Name	A label for the EMV application associated with a card brand (e.g., Visa, Mastercard). Helps identify which application the terminal will use when a chip card is inserted.
Contact	Indicates whether the AID is enabled for contact (chip-insert) transactions. If disabled, the terminal won’t use that AID for chip-insert processing.
Contactless	Indicates whether the AID is enabled for contactless (tap) transactions. If disabled, the terminal won’t use that AID for tap-to-pay.
PIN Bypass	Controls whether the terminal allows a customer to skip entering a PIN when prompted. Often used for low-value transactions or specific merchant preferences
Stand-in	Determines whether the terminal can approve certain transactions locally when it can’t reach the host. Useful for keeping transactions flowing during brief communication outages

General
AID	Specifies the Application Identifier used to route and process EMV transactions.

EMV CAPK Configuration

EMV CAPK Configuration is Read-Only. Information is sent from the Verifone Commander.

CAPK configuration loads the public keys the Verifone Commander uses to verify a chip card during offline authentication. Each card brand has its own CAPKs, and the terminal must store them to validate EMV digital signatures. Keeping CAPKs updated ensures the terminal can trust chip data and reject counterfeit cards.

Field/Button	Description
CAPK ID	A unique identifier for a specific public key used by a card brand. It tells the terminal which key it’s working with during EMV authentication.
RID (Registered Application Provider Identifier	A 5-byte identifier assigned to each card brand or payment network. It groups CAPKs by brand (e.g., Visa, Mastercard, American Express).
Index	A 1-byte value that distinguishes different keys under the same RID.Since a brand can have multiple CAPKs,, the index tells the terminal which exact key to use.
Expiry	The date when the CAPK is no longer valid. Terminals must remove or replace expired keys to ensure secure EMV authentication

Commander Payments

U.S. Debit Rules

Select Configuration Type	Choose the EMV profile based on whether the terminal operates inside the store or at an outdoor payment point.
US Debit - PIN Preferring	Prioritizes PIN-based authentication for US Debit transactions when available.
US Debit - No PIN	Allows US Debit transactions to process without requiring a PIN when permitted by the card and network.
