# Device Overview
This chapter provides a brief description of the Verifone M440 device.
The Verifone M440 device is a best-in-class, single-screen media-capable, and consumer-facing device, which allows electronic payment transactions to be processed in multi-lane scenarios. This payment processing solution with a fully integrated POS (Point-of-Sale) can scan barcodes, QR (Quick Response) codes, and products with the help of the integrated camera.
In combination with Verifone Connect digital services, it offers self-check-out/selfcheck-in, payment, and 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 Verifone M440 device supports Bluetooth and Wi-Fi (Wireless Fidelity) and meets PCI (Payment Card Industry)-PTS (PIN Transaction Security) 5.x SRED (Secure Reading and Exchange of Data) requirements for maximum security.
The Verifone M440 device supports all payment methods - magnetic stripe, EMV (Europay, MasterCard and Visa Standard), and NFC (Near Field Communication)/ CTLS (Contactless) Reader, including Apple Pay, Google Pay, and Samsung Pay mobile wallets. The easy-to-read color touchscreen supports all payment-related user interactions and keypads for secure PIN Entry.

## 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/m440/m440-installation-guide/device-overview.md?ask=&goal=
```
`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.
