Your First Transaction

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 Start Transaction – 0x1001 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 Transaction Information Update – 0x0101 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 Transaction Operation Complete – 0x0105 with the result.

Go deeper

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