## Introduction ### Terminal Overview A media-capable consumer-facing device that connects to a POS system which allows electronic payment transactions to be processed in multi-lane scenarios. It provides better media capabilities, more reliable hardware, and more efficient processing software. The terminal features a color 5” IPS LCD capacitive touch screen display, fast processor, abundant memory, PCI 4.x security, and an integrated contactless module. ### Features and Benefits The terminal focuses on optimizing cost structure and providing better form factor by combining the right features and functions. #### Exceptional Ease of Use * Large 5” LCD display for unlimited application possibilities and easy readability under various lighting conditions. * Touchscreen for icon-based applications or electronic signature capture support. * Intuitive telco-style keypad with colored control keys, interchangeably detects key presses from tactile keypad and the touchscreen. * Bi-directional magnetic stripe card reader with an extended blade for optimal card reading. * Audio jack to facilitate accessibility for the visually impaired. #### Performance and Durability * Fast transactions due to powerful 1 GHz ARM Cortex A9 processor. * Rounded corners and drop resistant to three feet on concrete floor to minimize breakage. * 256 MB of flash memory and 512 MB SDRAM with removable uSD. #### Security * Incorporates tamper-detection circuitry to resist unauthorized intrusion and supports a broad spectrum of software-based security features. * PCI 4.x approved for debit and other PIN-based transactions. * EMV Level 1 Type Approval. * Supports reliable security available including SSL, VeriShield file authentication, and VeriShield Protect to help prevent fraud and other intrusions. * With Kensington lock feature resident in the terminal as part of the case. #### Contactless Capability * Advanced contactless architecture that future-proofs investment with a single contactless interface (SingleCl), SoftSAMs, and side-by-side application architecture. * On-screen tap zone for optimized user experience. * Accepts EMV, NFC, and mag-stripe contactless payments as well as PIN-based transactions. ### Requirements #### Hardware * Verifone Commander, RubyCi, Commander 16 * Verifone C18, Topaz, Ruby2 * Verifone USB OTG Host cable (P/N CBL132-003-01-A) for loading software #### Software * Verifone Commander Software Base 49.00.00 and higher * Verifone EVPAY Version 2.00.10.00 and higher --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://commanderhelp.verifone.com/customer-documentation/petro-and-c-store/pin-pads/implementation-guides/m400.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.
