PAX A80

The PAX A80 exemplifies everything a dedicated countertop payment terminal should be: fast, reliable, and built to handle the demands of high-volume environments day after day. When you need a terminal that simply works, the A80 delivers.

Featuring a 4-inch color touchscreen, the A80 provides clear transaction information and intuitive operation. The large display shows payment amounts clearly to customers, reducing errors and building trust. Physical buttons remain available for those who prefer traditional terminal interaction.

Processing speed is where the A80 truly shines. Transaction times under 2 seconds are routine, making the A80 ideal for environments where speed matters—busy retail counters, quick-service restaurants, and anywhere lines form during peak periods. The integrated high-speed printer keeps pace with rapid transactions.

The A80's compact footprint takes minimal counter space while its robust construction handles commercial use. Ethernet connectivity provides reliable, fast communication, while dial-up backup ensures you can process payments even if your internet fails.

The payment terminal market includes devices from Clover, PAX, Dejavoo, Ingenico, Verifone, and Square. Here is how the PAX A80 stands out.

vs Entry-Level Terminals

• Advanced reporting, employee management, and inventory tracking
• PCI-PTS certification with point-to-point encryption
• Customer engagement features built in

vs Proprietary Systems (Square, Stripe)

• Interchange-plus pricing saves 20–40% vs flat-rate
• No processor lock-in — you own the pricing relationship
• More hardware accessories and peripheral support

Integration Ecosystem

Kitchen displays, barcode scanners, cash drawers, and customer-facing screens — all configured by Unison's team so everything works together from day one.

Every card transaction involves three fee layers. Understanding them is the first step to paying less.

The Three Fee Layers

• Interchange — set by Visa/Mastercard, paid to the issuing bank (non-negotiable)
• Assessment — charged by the card network (non-negotiable)
• Processor markup — the only negotiable part of your fees

Interchange-Plus vs Flat-Rate

Flat-rate processors (Square at 2.6% + 10¢, Stripe at 2.9% + 30¢) charge the same on every transaction. That means you overpay on debit cards where actual interchange is often under 0.5%.

Unison's interchange-plus pricing shows you the real cost. The average business saves 20–40% after switching. Read our guide to lowering fees.
