This walkthrough runs one EMV sale end to end so you can confirm your setup works. It's the quick version — each step links into the full detail.

Before you begin

• Your reader is connected — see Connection Basics.

• Keys are injected and you can decrypt output — see Security & Key Management.

Run it

1. Start the transaction. Send with the amount and transaction type, and prompt the cardholder to insert, tap, or swipe.

2. React to the reader. As the transaction proceeds, the reader sends notifications reporting progress. On a reader without a display (like the DynaFlex II Go), respond to any prompts it sends via Host Action Request.

3. Finish. The reader produces an ARQC; forward it to your processor and return the response, or use Quick Chip to complete immediately. The reader sends with the result.

That's the shape of it. For the full flow — the Quick Chip vs. EMV fork, online authorization, contactless, and configuration — see .

DynaFamily readers connect to a host over USB or Bluetooth LE. The MMS command set is identical over either transport — how you frame and send commands doesn't change — so the connection choice is about the device and your use case, not your integration code. Wired USB is simplest for fixed, attended setups; Bluetooth LE suits portable and mobile deployments (on the readers that support it, such as the DynaFlex II Go).

Once connected, head to , or the for the command set.

Get started is the on-ramp for building with MagTek products. It takes you from choosing a device to running your first transaction — the connection basics, the minimum steps to see a card read end to end, and where to go next. If you're new to the platform, start here; once you're up and running, the Guides and the API & Command Reference cover the depth.

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.

Compare the readers

All are PCI PTS POI–approved SCRAs with EMV L1/L2/L3 support and SRED point-to-point encryption.

• Need to accept PIN debit? The 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 is portable and battery-powered, and it's the one with Bluetooth LE.

• Attended countertop, no PIN? The is the compact fixed reader.

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

Want to see a reader work before you write any code? MagTek's browser-based demos lets you connect a device and run commands straight from your browser using WebHID — no SDK install required.
