Devices

Learn about the different devices that we offer.

We support four different types of devices:

  • Portable: a compact, battery-powered payment terminal that can be deployed in mobile or temporary locations, allowing for self-service transactions without fixed infrastructure. Ideal for events, food trucks, or temporary retail installations.
  • Mobile: a flexible terminal to accept payments wherever your business takes you. Ideal for small merchants and mobile payment scenarios like taxis, delivery services, outdoor vendors, and more.
  • Countertop: a stationary terminal designed to sit on a checkout counter or desk. Ideal for businesses that conduct transactions from a fixed location, such as traditional retail stores.
  • Unattended: a self-service payment terminal that allows customers to complete transactions independently, without the need for staff intervention. Ideal for vending machines, self-service kiosks, and automated fuel pumps.

Each device comes with the PXP application already installed.
