Quick Answer
Mobile POS systems typically have lower upfront costs ($0–$300) but higher processing rates (2.6%+), while countertop terminals require more initial investment ($300–$800) but often offer lower rates (1.5–2.5%). Choose mobile for flexibility and low startup costs; choose countertop for high-volume, fixed-location businesses focused on minimizing per-transaction fees.
