How Square Prepares Digital Tabs for Customers Before They Arrive

A system that lets merchants create a digital customer tab before a guest arrives, using reservation data to pre-load preferences and payment info for a faster checkout.

What it covers

This patent describes a way for point-of-sale (POS) systems to start a transaction record before a customer even walks through the door. When a customer makes a reservation or joins a waitlist, the system creates a data structure—essentially a digital tab—that stores the customer's ID and arrival time. When the system detects the customer has arrived, it automatically displays this pre-populated tab on the merchant's screen. This allows staff to instantly see the customer's preferences or pre-saved payment information, making the actual ordering and payment process much faster.

What it doesn't cover

• —Does not cover general reservation systems that only track time and headcount without linking to a POS transaction data structure.
• —Does not cover automated payment processing that occurs without a merchant-side POS device display.
• —Does not cover systems that rely solely on proximity beacons without a prior reservation or waitlist request.

The clever bit

The innovation is treating a future reservation not just as a calendar entry, but as the 'start' of a transaction data structure that can be enriched with payment and preference data before the customer is physically present.

Why it matters

This technology bridges the gap between booking software and payment hardware. By turning a reservation into an active, pre-loaded digital tab, merchants can reduce friction at the point of sale. It is a key component of the modern 'frictionless' retail experience where the payment happens in the background.
