Key Term: Issuer Processor The Issuer needs a technology provider that can connect with the payment networks. Usually, the Issuer Processor will have a piece of hardware in their data centers and a fast network connection directly to the payment networks to approve or decline a transaction. Sometimes, the Issuer may have built this technology in-house or may rely on a third-party Issuer Processor to handle this. Examples include Marqeta, Tsys, Galileo, i2c.
