Abstract: In some embodiments, a verification system includes a memory storing a common identifier that identifies a user. The system may also include one or more hardware processors coupled to the memory and configured to read instructions from the memory to perform the steps of: receiving a token associated with a request to complete a transaction with an environment; determining the common identifier associated with the token, the common identifier being associated with an identifier of the merchant, an identifier of the user requesting the transaction, and a funding instrument associated with the user; and determining, based on information associated with the common identifier, whether to approve the transaction.

Abstract: A method for verifying transactions is discussed. The method includes receiving a transaction request for performing a transaction between a user account and a merchant account. The method includes determining, based on authentication of the user account, a common identifier associated with the user account, the common identifier indicating the user account being authorized for use at a plurality of merchant accounts including the merchant account. The method includes determining a payment token for performing the transaction, the determining the payment token based on the common identifier and a user associated with the user account. The method also includes providing the payment token for completing the transaction.
