Size terminal count from peak transaction rate and acceptable line length. If one checkout averages 45 seconds, one terminal can theoretically process about 80 transactions per hour with no interruptions; real throughput will be lower.
Run a timed rehearsal with the actual menu and tipping screen. A slow modifier flow can double checkout time compared with a simple two-item menu.
A second terminal is not only capacity—it is backup if one device loses power or connectivity. For high-revenue festivals, redundancy often pays for itself quickly.
For “How Many POS Terminals Does an Event Vendor Need?,” these three models give you concrete products to compare against the requirements above, instead of leaving the answer at theory.
Our strongest starting point because it is handheld pos in the square ecosystem—useful for deciding how much hardware and connectivity the event workflow actually needs.
A useful second comparison because it is all-in-one terminal in the square ecosystem—useful for deciding how much hardware and connectivity the event workflow actually needs.
A contrasting third option because it is contactless + chip reader in the requires compatible square app/device—useful for deciding how much hardware and connectivity the event workflow actually needs.
