# Device Overview

The Verifone M425 is a new Multi-Lane, media-capable and consumer-facing device. M425 device's enriching features allow electronic payment transactions to be processed in multi-lane scenarios with combined card payment with a variety of Verifone cloud-based services including Advanced Payment Methods, e-comm capabilities such as Buy Online Pick-Up in Store, and the ability to dynamically configure multi-media driven promotional content at the counter.

This payment processing device can scan barcodes, QR codes, and products with the help of an integrated camera. In combination with Verifone Connect digital services, it offers the ability to run Android applications, like loyalty and inventory.It also enables clients to remotely monitor and update their devices using Verifone's estate management solution.

The best-in-class M425 device will be able to communicate to the ECR via serial over USB and IP over USB simultaneously and support multiple SAM cards for transaction processing. Verbal Message Supporter is a new significant feature where the user will be able to speak into the terminal microphone to state their issue or raise a question that will be received by the Verifone Support Administrator. It also supports video playback from a serial digital memory interface to play training videos for staff and promotional content to customers at or near the checkout counter or in the lane. It transforms the customer's journey into a simple walk-through by providing different connection options like an external power supply, USB, and ethernet.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.verifone.com/hardware-products/hardware/engage-devices/m4xx-series/m425/m425-installation-guide/device-overview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
