ISO 8583 simulator Environment
You will love having the same simulator for all your connections: Visa, MasterCard, Bank host, ATM, POS, e-commerce.
Visa, MasterCard, Amex
simulated with the standard ISO8583 based package
POS devices, network
various POS protocols, fixed message or ISO0503 based
ATM devices, network
depending on the device handler, NCR, NDC, Diebold
Clearing and settlement
simple fixed formats configurable, as well as XML or JSON
PSP, aggregator
usually via some form of ISO8583 implementation, easy to configure
e-commerce gateways
they usually send some implementation of ISO8583
e-commerce APIs
standard HTTP web service with XML or JSON data
mobile commerce, networks
networks usually come via ISO8583, while devices may send any API form
telephone, mail
simplified ISO8583 or customized messages, SQL to database checks
Iso8583 simulator Setup Layout
Test Data
All test cases are stored in Excel sheets. So does card data, key data, validation data and authorization rules. Other sources are possible.
Connections
Easy UI configuration, stored in JSON format in javascript file, easy version control.
Messages
Easy to configure via UI, but also via javascript JSON editing directly, so easy to deliver, store and massively update.
Business logic
javascript is key here. We use it to user menus for transactions, build transaction data, call core features and of course, handle message contents. The user can see all its work.
Authorization logic
Configurable authorization rules and validation are available in Excel, but more logic is built into javascript authorization, like when to do cryptogram checks and PIN validation, or when to override default response codes
neaPay Core
The power of our simulator comes from its script engine, with support for connections, message building and formatting, its look and feel are the UI which makes it all easy, but its heart is the controller which manages it all.
The UI
It is responsible to make it all pleasant for you to configure connections, messages and fields.
The Engine
It is responsible for running the scripts and do the processing.
The Controller
handles the connections, provides and handles data to and from the script engine and UI, as well as files, databases or TCP/IP.

ISO8583 simulator usage scenarios
Acquire or issue against schemes and devices — same engine, different scripts and test packs
Visa
Visa Acquirer Issuer simulator
Acquiring from Visa can be easily simulated by our neaPay engine. How does it work? Load the Visa scripts in our simulator engine, the Visa message format, and do not forget the test cases. Make sure you point to the IP and port you need and start firing away those transactions like they came from Visa. Authorize in your system and our scripts will wait for the response to validate.
Visa Issuer is loaded the same way, just use authorization scripts for issuing, and select the connection type to be a server. The scripts know what messages to wait for, process and respond. Use it for internal regression and continuous testing alongside your scheme certification simulators — validate every release before production, not just at scheme onboarding.
MasterCard
MasterCard Acquirer Issuer simulator
MasterCard Acquiring is just as easy. Load the BankNet scripts, as well as the messages and test cases, point the simulator to your system and run transactions. One by one, in batches or in full regression mode, it is all a matter of choice. All messages go out in parallel and can come back in any order. Just like a real authorization system.
MasterCard Issuing works with the same scripts, but uses the issuer part of them. The logic in the scripts decides that when you select the option to listen as a server.
Schemes
Diners, Amex, JCB, CUP simulator
Diners, Amex, JCB, China Union Pay? For the engine it is a matter of loading a different script and formatting messages differently. For the tester it is just a difference of test cases. And IP/port.
Acquiring or issuing, that is just an option.
Run reliable regression and performance testing beyond what scheme certification simulators cover — complementary internal validation for every release.
Payment switches and banks use neaPay to test member connections and in-house processing without building their own simulator.
Devices
POS, ATM and e-commerce simulator
POS and e-commerce transactions work just as easily. Load the scripts, the transactions and start testing. Or make changes to match your custom interfaces, and then test as much as you want.
Each ATM vendor comes with a different format and it may be a little more complicated. To be honest, if your vendor provides a simulator for the ATM, use that one. If you need something heavily customized, then neaPay's engine will definitely be able to do it. Contact us and tell us what device you have, we might have the scripts for it already. If not, it is never too late to write a new one.
Regression Testing
Ensuring your payments system did not lose any functionality on updates. Check and validate that limits are working just as fine as before, that the accounts are debited and usages are updated. Each of them. A good regression pack can detect whether your limits are working fine, your balances are fine, all your fields are formatted correctly, for each transaction type, and your transactions are approved or declined as before. With that peace of mind, you can proceed to test the enhancements. Our simulators are designed with a regression approach from the beginning, therefore, any new functionality can be easily added to the regression pack, so next time you apply changes, these enhancements will be tested as part of the regression. After a few years, you will have a nice regression pack of a few hundred or thousand transactions, which can be run in less than an hour to check the status of the system, any day or night. You want this, we know you do, and our simulator can do it very well.
Automatic Regression Testing
We know that you need the functionality above and you know you want it executed as soon as possible. What is your estimate for running a complete regression for the system, that covers everything, with 1000 test cases? You may say a week, you may say maybe two, or you may dare to estimate 2 days. We say that takes an hour. Because that is the estimate we wanted in our test plans and we made the simulator that can do that. Once all is set up properly, click the Run and go for a coffee. When you come back, you have your answer.
Performance Testing
Your system must do all the processing at very high speed, so we built a matching simulator, which can run just as fast. We believe that 60 transactions need to be run in 3 seconds, not 30. We hope you agree. So our simulator can run fast enough to be used for performance testing, even without caching features. We have in plan to add a caching feature, which can release hundreds of transactions per second, it will be here soon!
Frequently Asked Questions
Architecture, deployment, scale and time-to-live for the ISO8583 Simulator
The application Core is written in Java, runs on any platform where Java is available. The configuration and behavior are written in JavaScript, 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 simulators 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 simulator instance can run its own configuration to perform a separate task.
Several simulators 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 ISO8583 Simulator 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
