The e285 device is a standalone, wireless handheld payment device, making it easy to process a transaction anywhere. It provides mobile payment capabilities via 3G connectivity. It is also a powerful 3G/Bluetooth/Wi-Fi dual-band solution, featuring advanced communications for fewer dropped transactions so merchants can accept payments securely, extending their point-of-sale opportunities. The e285's capacitive touch with physical keypad design makes it easily pocketable while still accepting all payment methods — MSR, PSCR, contactless, and wallets. The easy-to-read color touchscreen is capable of signature capture and is fully supported by Verifone's developer toolkit, which enables ideas to be transformed into applications.

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/exxx-series/e285/e285-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.
