Walker C2X Details

Walker C2X is a compact, powerful card reader that supports EMV Chip & Sign, contactless payments like Apple Pay and Android Pay, and magstripe payment technologies.

For convenience, a removable sticky pad is available to firmly adhere the card reader to a paired device.

Walker C2X’s embedded card reader expands a merchant’s ability to process card-present transactions anytime, anywhere via swipe, dip or tap. The device is also well suited for enterprise applications, whether part of a fixed tablet POS, or when integrated with mobile line-busting and tableside payment applications.

Firmware updates and key injection are supported via remote OTA (Over-the-Air) transmission, ensuring the device stays current. Walker C2X can be integrated with POS and payment apps using intuitive APIs and SDK developer tools or can be part of an end-to-end custom mobile payment solution.
