Scan To Pay (STP)

Modified on Thu, 11 Apr 2024 at 11:32 PM



Scan To Pay offers drive-up customers a quick parking purchase experience. Parkers interact with a sign by scanning a QR code or tapping a NFC tag.  They are then routed to an instant checkout to quickly purchase and view their parking pass.

STP User Flow

The driver enters and parks in an open space, scans the App Clip or QR code on the sign, selects a designated parking duration and rate, and then pays to secure the session. The license plate is collected for enforcement. The payment is reconciled upfront upon checkout completion.

The STP signs may be posted on poles, fences, bollards, wind signs, or elsewhere depending on the lot layout.
