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 test card reader of your choice, connectivity and power supply cables, and one test card. You can also order additional test cards.

Available test card reader models include:

Verifone e355

Verifone VX820

Miura M010

PAX A920

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