ISO8583 EMV QR Code Converter Interface

Connect and Integrate ISO8583 or other formats

QR Code Payments Integrations

with QR image generation

and converting from payments formats like ISO8583, ISO20022 , SWIFT or APIs

Integrate with existing card payments processing systems

Easy integrate cryptography to achieve compliance

Integrating an older standard like ISO 8583 with a modern payment method like QR codes requires specialized middleware to translate the formats and manage the diverse payment flow. The core challenge is converting a binary, fixed-format message (ISO 8583) into a flexible, data-rich digital payload (QR Code standards like EMVCo, UPI, or local schemes), and vice-versa.

The required solution is a dedicated Payment Interface and Converter, often part of a broader Payment Switch architecture.

EMV QR Code payments integration

The features center on flexibility, compliance, and interoperability to manage the differences between the two standards.

Translation and Interoperability

Bi-directional Protocol Conversion

Seamless conversion of transaction requests and responses between the ISO 8583 binary message format and the QR code's data structure (e.g., JSON, TLV, XML).

Multiple QR Standard Support

Built-in support for global and regional QR specifications, including EMVCo QR Code, UPI (India), and various national scheme formats.

Custom Data Mapping

A configurable engine to map non-standard QR data elements into available or private ISO 8583 data elements (DEs 100-128).

Security and Compliance

Tokenization & Decryptor

Ability to use QR data (such as a card token) to retrieve the actual Primary Account Number (PAN) from a token vault and map it to ISO 8583 DE 2, all within a PCI-compliant environment.

Cryptographic Services

Integrated functions for generating and validating the Message Authentication Code (MAC) for ISO 8583 messages (DE 53) and the digital signature/cryptogram for the QR payload.

Fraud Monitoring Integration

Ability to extract rich data from the QR payload (e.g., device ID, location data) and inject it into the ISO 8583 message (often via private fields) for the fraud system to analyze.

Non-Stop Availability

Deployment in containers (Docker/Kubernetes) to ensure horizontal scaling and resilience for 24/7/365 payment operations.

Automatic Stand-In

Logic to approve low-value QR transactions when the core host is temporarily unavailable, maintaining user experience.

High-Volume Processing

A microservices-based architecture to ensure high Transactions Per Second (TPS) to handle the increased load from digital payments.

Frequently Asked Questions

The application Core is written in Java, runs on any platform where Java is availableThe configuration and behavior are written in JavScript, which is delivered to the customer

Most users run the POC on a workstation or Windows VM, but some use Mac or Linux platforms for initial acceptance
Non-stop and high load converters run on Linux servers or containers
Any cloud can be used, as long as it runs Docker Containers and an OS that supports Java. RedHat, Ubuntu, CentOS

As a microservice, each converter instance can run its own configuration to perform a separate task
Several converters can be run at the same time for ISO8583, ISO 20022, SQL/Oracle, Visa, Amex, MasterCard, clearing
Each microservice can therefore be redeployed, reconfigured and maintained separately

All connectivity, message formats, business logic, are usually delivered pre-configured, ready to run.
The customer can change all of the above, on-premise.
All configuration is easy to version-control (via git)

Super fast. Processing time is under 1 millisecond.
It can be limited by external IO, HSM, Database, of course.
Each microservice instance can be scaled separately, depending on load.
Scale with containers, service managers, or simply starting several instances and balancing them via the neaPay Switch-Router

POC in a couple of days. MVP in a couple of weeks.
Most common formats are already available.
The neaPay card payments ISO8583 converter can be set up for a POC in a few hours.
Depending on the size of the scope, we can get the most of it set up and tested in a few weeks.
We can then validate and go Live in 1-2 Months. Get a Free Price Quote
