This feature is ideal for collecting non-payment card data via magnetic stripe, supporting applications like loyalty card programs. > **Note:** Allowlisting is currently supported only via the magnetic stripe reader and is not available for chip or contactless transactions. # **Submitting an Allowlist for Approval** To enable allowlisting on a payment device, you’ll need to follow strict security guidelines. Please contact NMI support at with the following information: * **BIN Range:** Provide a BIN (Bank Identification Number) range for the allowlist. Ensure that this range is not associated with payment cards, as such requests will be denied. * Example: 123456 0000 0000 (start) - 123456 9999 9999 (end) * **Card Number Length:** Typically between 12–16 digits. * **Payment Device:** Confirm that your device supports allowlisting by referencing the supported devices list above. * **NMI Payment Device SDK:** Specify the platform (e.g., Android, iOS, or Windows). * **Application Scope:** Indicate whether the allowlist applies to an entire device estate or to specific merchants. > **Important:** The allowlisting process may take several days, as it requires secure approval to maintain data integrity.
