# Pick Your Dyna Device

Every reader in the DynaFamily speaks the same MMS command set, so your integration is largely portable across them — the differences are form factor, whether the reader takes a PIN, and how it connects. Use the table below  to narrow down, then open a product hub for full specs.

### How to choose

* **Need to accept PIN debit?** The [<mark style="color:red;">**DynaFlex II PED**</mark>](https://developer.magtek.com/products/dynafamily-mms-dyna-devices/dynaflex-ii-ped) is the only one with a PIN pad — it's also the one with a full touch display for on-screen prompts.
* **Mobile or handheld?** The [<mark style="color:red;">**DynaFlex II Go**</mark>](https://developer.magtek.com/products/dynafamily-mms-dyna-devices/dynaflex-ii-go) is portable and battery-powered, and it's the one with Bluetooth LE.
* **Attended countertop, no PIN?** The [<mark style="color:red;">**DynaFlex II SCR**</mark>](https://developer.magtek.com/products/dynafamily-mms-dyna-devices/dynaflex-ii-scr) is the compact fixed reader.
* **Contactless/tap only?** The [<mark style="color:red;">**DynaProx**</mark>](https://developer.magtek.com/products/dynafamily-mms-dyna-devices/dynaprox) is contactless-focused.

Because they share the command set, you can confirm exactly which commands a given reader supports in the DynaFamily Command Matrix, and see full specs and downloads on each product hub.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://developer.magtek.com/get-started/pick-your-dyna-device.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.
