## Features and Benefits
The V205c terminal provides the following functionality:
### Ease of Use and Ergonomics
* Four-way navigation button with two selection keys for UI (User Interaction) access.
* The contactless functionality offers a convenient payment option for consumers.
* The bold design is sleek, stylish, and lightweight for conveniently handing the terminal to the consumer for a PIN (Personal Identification Number) entry or other input.
* A large 8-line by 21-character backlit display with a backlit keypad, and extra size menu prompts, simplify training, and reduce help desk calls.
* The multiple font-capable integrated thermal printer simplifies paper loading and reduces paper jams. Uses 57 mm wide x 40 mm diameter paper rolls, and prints at 30 lines per second (LPS).
* The triple-track, high-coercivity card reader handles most magnetic stripe cards.
* Large, hard-rubber keys provide improved tactile feedback.
* Intuitive keypad interface simplifies training and reduces support requests.
* Connects with most POS (Point-of-Sale) payment terminals, PCs (Personal Computer), and ECRs (Electronic Cash Register).
* Supports payment transactions in a variety of payment environments.
* Rugged and reliable design absorbs hard knocks found at point-of-sale counters.
* Sleek and stylish shape occupies minimal counter space.
### Critical Security Protection
* Offers a choice of Master/Session or DUKPT (Derived Unique Key Per Transaction) key-management methods to protect PIN-based transactions.
* The primary smart card reader and the MSAMs safeguard sensitive financial data and support multiple smart card schemes.
* Certified for ISO7816-3, ISO7816-10 and EMV (Europay, MasterCard, and Visa) 4.3 standards for smart card solutions.
* Offers secure, reliable PIN input for expanding the range of PIN-based transactions.
* PCI 5.x-compliant for secure solutions, meeting the PED (PIN Entry Device) standard.
* Meets ISO (International Organization for Standardization) and ANSI (American National Standards Institute) standards for PIN encryption, key management, and MAC (Message Authentication Code).
* The VeriShield security architecture meets published specifications for PCI (Payment Card Industry) PTS (PIN Transaction Security) POI (Point-of-Interaction) and provides sophisticated file authentication to prevent the execution of unauthorized software.
* Key injection simplified and secured with Verifone's SecureKit key loading software.
### Countertop Performance in a Hand-Over Design
* The 32-bit processing and multi-tasking capabilities ensures fast processing of payment, payment-related, and value-added applications.
* Exceptional display and printer graphics-handling capabilities that quickly render logos, graphical fonts, and character-based languages.

## 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/vxxx-series/v205c/v205c-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.
