Developer Kits

After integrating payments into your point-of sale (POS) system using the Mock mode, it is time to see payments in action with a real card reader.

When you order a developer kit, you will receive the PAX or Miura test card reader of your choice, accessories, and one test card. You can also order additional test cards.

Test card readers can only be used in Test Mode. To go live, order live card readers.
