Workshop Title:

From tap to auth: Building a complete payment processing flow in Go

Time:

Tuesday - 10:30 AM (Tower A)

Abstract:

In this hands-on workshop, participants will build a complete payment processing pipeline using Go. You’ll create each component of the transaction flow that powers billions of payments worldwide: from contactless card reading, through acquirer processing, to issuer authorization.

We’ll use open source modules for ISO 8583, BER-TLV, EMV, and NFC. With test payment cards and Go packages, you’ll implement a terminal that reads card data, an acquirer that transforms messages, and connect to an issuer that provides authorization decisions.

This workshop brings to life payment concepts often only discussed theoretically. All necessary hardware and test cards will be provided, with code templates ensuring success regardless of prior Go experience.
