Merchant ID Registration

A

Barclays

MID is a unique value within

Barclays

that you define during account registration. Your MID identifies your merchant account and payment configuration within

Barclays

systems. You provide this identifier when you sign in to the

Smartpay Fuse Portal

and submit transactions to

Barclays

.

Multiple MIDs can be configured for various token types. You receive the instrument identifier token regardless of your account’s token type. Reasons for multiple MIDs include:

You have multiple processors.
Point-of-sale terminals have unique MIDs, which are usually configured for the PAN-only instrument identifier token.

When you have multiple MIDs, you can set up one token vault to which all of your MIDs have access or set up multiple vaults to limit access to tokens. See Token Vault Management for more information on setting up and managing your token vault.
