# DynaFamily Command Matrix

Every MMS command is documented once in this reference. This matrix shows which commands each DynaFamily reader supports, so you can confirm availability before building against a device. A command marked — is not available on that device's current firmware; some commands depend on a hardware option (noted below the table).

**Legend:** ✓ supported · — not supported

### Notes on device-specific commands

* **PIN / banking** (Request PIN) require a PIN-entry device — **PED only**.
* **Bluetooth LE** commands (Terminate Connection, Erase Bonds) require a BLE radio — **DynaFlex II Go only** among these; corded devices omit them.
* **Full-display UI** commands (Display Message, Show Image / QR / Bitmap, Flexible UI Pages, Request Cardholder Signature) require the full touch display — DynaFlex II **PED only**.
* **Read Barcode** requires the barcode-reader (BCR) hardware option.
* **Establish Ephemeral KBPK** is a provisioning/manufacturing command — confirm whether it should be publicly listed or kept to an internal space.

# 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/api-and-command-reference/dynafamily-command-matrix.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.
