Device connectivity and card interfaces

Review supported communications interfaces, card reading capabilities, and SDI extension points.

VOS3 provides standard communications interfaces on the application processor and protected card access through the secure processor and SDI.

Use this page to review supported connectivity features and card interface capabilities.

Connectivity functions

Card reading functions

Card Function	Support
MSR	3-track magnetic stripe reader ISO 7811 JIS1 JIS2 Samsung Pay US driving license cards such as AAMVA and CADL-ID
ICC chip card	Yes
RFID contactless cards	ISO cards MiFare
Synchronous cards	No support
EMV processing	Contact Contactless

Customization

VOS3 supports system plug-ins for card-scheme-specific processing that must run inside SDI with access to protected card data.

Verifone supports this work with application teams when a deployment needs custom card handling.

Hardware interfaces

Resource identifier strings

Each device has a UI resource identifier string that reflects its screen resolution, color depth, keypad presence, and touch capability. Use this string when selecting device-specific UI assets.

Device	Screen resolution (px)	Touch	Keypad	Resource identifier
P630	320 × 480	Yes	Yes	320x480C15T
M425	1280 × 720	Yes	Yes	1280x720C15T
M450	1280 × 800	Yes	Yes	1280x800C15T
Ux700-AIO / Ux700-ML	720 × 1280	Yes	No	720x1280C0T
V220p	320 × 480	Yes	Yes	320x480C15T
e240 / e245	320 × 240	Yes	Yes	320x240C15T

Connectivity options

Available ports depend on the USB Mode setting configured on the device. Switch between USB Device and USB Host mode in the Communication Control Panel.

Some use cases require the Verifone Unified USB Driver installed on Windows, specifically for the RNDIS Ethernet gadget interface.
