Dejavoo QD4 vs. Other Terminals

QD4 vs. PAX A80

The PAX A80 has a smaller 4-inch screen but is more compact and slightly more affordable. Choose the QD4 if screen size and battery life are priorities. Choose the A80 for tighter counter spaces and lower cost.

QD4 vs. Dejavoo QD2

The QD2 is the mobile version — smaller, lighter, and fully portable. The QD4 is the countertop powerhouse with a bigger screen and dual batteries. Choose the QD2 for on-the-go, QD4 for countertop use.

QD4 vs. Verifone V400m

The V400m is a similar countertop competitor. The QD4 has a larger screen (5.5″ vs 4″) and better battery life. The V400m may be preferred if your processor requires Verifone-specific integrations.
