Stand-In Authorization
MercuryStand-In is a unique service that Mercury Payment Systems developed to keep merchants processing during outages in the authorization network.

Imagine payment processing screeching to a halt just when sales traffic is at its peak. Checkout lines get longer. Customers get angry. Staff gets frustrated. Problems escalate.

Not with Mercury. MercuryStand-In™ guarantees continuous processing.

If a processing outage occurs, we turn on our unique "stand in" authorization service. We developed this essential service so our merchants keep processing if there’s an outage within the authorization network. We "stand in"—so business continues as usual. While standing in, we approve all transactions up to the floor limit, and guarantee no financial loss to our merchants.
