TAP-4
The whole bar in one hand
The TAP-4 is the device in every vendor’s hand. Stripe-grade payment hardware running wrstPOS, it accepts RFID cashless, Apple Pay, Google Pay, and cards; it can also enroll wristbands and cashless accounts in the field; and it processes offline so the line never stops because the signal did.
