ICCSimTMat for Fiserv
The general-purpose TMat packaged with the workflow, test suites, cards and portal integration needed for Fiserv projects. It is aimed at merchants, ISVs and terminal vendors connecting to Fiserv.
A capable, straightforward EMV test and certification kit developed for Fiserv merchants and ISVs. Built on the established ICCSimTMat EMV test suites, it carries test cases qualified by the major schemes and needs neither complex hardware nor large numbers of cards. It links to the Fiserv portal for project access and for uploading logs during and after testing.
What this kit offers
What ICCSimTMat for Fiserv contains and what it does.
Integrates directly with the Fiserv portal. You can access projects and upload logs throughout the test lifecycle, both during and after testing.
- Direct access to projects
- Log upload during and after testing
- A more efficient, connected certification process
Self-contained, with no extra components required. It removes the dependence on complex hardware, card adapters, separate capture tools and large numbers of cards, working instead from one integrated platform.
- No complex hardware, card adapter or separate capture tool required
- Test campaigns run faster, more efficiently and at lower cost
Everything needed for testing: the software, all test cards, the card reader/writer and first-year support.
- Software for testing the major schemes
- All the test cards required to run the tests
- The card reader/writer unit
- First-year support and maintenance, including the helpdesk
Online licensing removes the need for a USB key and adds flexibility. It is probe ready, so PaytestProbe can be used instead of cards, except for fallback testing.
- Online licensing, with no USB key
- Probe ready: supports PaytestProbe, except for fallback testing
- Options: a test card pack for post-development testing, and testing services
Test suites available
Examples of Level 2 and Level 3 test suites qualified by each scheme, as of the information sheet. We confirm the current position each time.

Specifications and schemes




Schemes supported for Fiserv (coverage depends on the configuration and licences)
Schemes supported: American Express, Discover, INTERAC US, Mastercard and Visa. This is the standard ICCSimTMat packaged for the Fiserv ecosystem. It is probe ready, supporting PaytestProbe. We confirm the details and current coverage each time.
Fiserv portal integration
The main difference from the general version of TMat is integration with the Fiserv portal. The connection to the Fiserv certification process is closer than managing files separately.
| What you can do |
|---|
| Access projects held on Fiserv |
| Retrieve test project information |
| Upload logs during testing or once it is complete |
| Link test results to the certification process |
Kit contents and configuration
| Category | Detail |
|---|---|
| Included | Software for testing the major schemes; the test cards needed to run the tests; the card reader/writer; first-year support and maintenance; and helpdesk access |
| Licensing | Online licensing; the traditional USB licence key is not required |
| Standard configuration | TMat for Fiserv with physical test cards |
| Configuration for automation and efficiency | TMat for Fiserv + PaytestProbe |
| Fallback testing | Requires a physical card with a magnetic stripe |
Rather than moving entirely to probes, you need to keep at least the cards used for fallback testing.
Choosing between the ICC Solutions products
The general-purpose ICCSimTMat, the Fiserv-only kit and the Worldpay-only VIABLE are clearly separated.
| Comparison | TMat | TMat for Fiserv | ICCSimDev | Merchant Cards | VIABLE |
|---|---|---|---|---|---|
| General purpose or dedicated | General purpose | Fiserv only | General-purpose development | General-purpose basic cards | Worldpay only |
| Primary audience | Vendors, laboratories and acquirers | Fiserv merchants and ISVs | EMV developers | Stores, maintenance and training | Worldpay merchants and ISVs |
| Level 2 | Suite available | Mainly Level 3 | Custom-developed testing | Not possible | Mainly Level 3 |
| Level 3 | Supported | Supported | Not for formal certification | Not possible | Supported |
| Host integration | External or simulated | Fiserv Portal integration | Outside its purpose | Requires a test host | Built-in closed loop |
| Negative testing | Scheme test case coverage | Fiserv test case coverage | Highly flexible | Limited | Worldpay test case coverage |
| Automated analysis | Yes | Yes | Focused on script development | No | Yes |
| Certification submission | Through suites | For Fiserv | Generally not possible | Not possible | For Worldpay |
| PaytestProbe | Supported | Supported | Focused on generated cards | Not supported | Supported |
Where the product sits in the process
On the issuance side, the Barnes and ICC Solutions products are not competitors; they sit at different stages of the process.
| Process stage | Product | Objective |
|---|---|---|
| Card issuance side | Barnes CPT | Inspects card data, certificates, EMV tags and magnetic stripe data |
| Card and terminal development | ICCSimDev | Develops error cards, custom cards and negative tests |
| Terminal kernel | ICCSimTMat Level 2 | Verifies the EMV kernel and reader application |
| Finished POS and ATM | ICCSimTMat Level 3 | Scheme integration testing |
| Specific acquirer | TMat for Fiserv / VIABLE | The Fiserv and Worldpay certification process |
| After store deployment | Merchant Test Cards | Quick checks, regression testing and staff training |
What we confirm before proposing
Before finalising a configuration we ask about the following.
| Category | Points to confirm |
|---|---|
| Test scope | How far coverage must extend across contact, contactless and magnetic stripe, and whether Level 2, Level 3 or both are needed |
| Scope | Which of POS, ATM, Tap to Phone, transit or fuel applies, and the exact scheme and test suite versions |
| Connects to | Which acquirer you connect to — Fiserv, Worldpay or another |
| Method | Whether physical ICCSim cards or PaytestProbe is used, whether physical cards for fallback testing are included, and whether a host simulator is required |
| Licences and maintenance | Maintenance charges after the first year and what happens if renewal stops, the expiry of the test cards, and how licences are divided between the scheme-qualified suites and development scripts |
| Automation | The API specification for Auto API and robot integration, and compatibility between cards generated in ICCSimDev and TMat |
| Domestic requirements | Is a dedicated L3 test plan available for the local acquirer or payment network? |
Supporting an international brand’s L3 suite and having the local acquirer or payment network accept that result as certification are two separate matters. We confirm the brand, acquirer, payment gateway and terminal configuration before fixing the product configuration.
Choosing the right ICC product
The ICC products divide by purpose. Where each sits is set out in the Level 3 layer.
| Product | If you are considering |
|---|---|
| ICCSimTMat | You need to pass formal scheme approval at Level 2 and Level 3, and want acceptance testing managed and run with qualified suites |
| ★ ICCSimTMat for Fiserv (this page) | Merchant and ISV certification through Fiserv, with test logs uploaded directly via the portal |
| ICCSimDev | You want to build your own card responses and error conditions, for negative testing and debugging |
| VIABLE | You want to run merchant and ISV acceptance testing together in a closed-loop store setup |
| Merchant Test Cards | You want physical cards for checking terminal configuration, regression and staff training |
| Testing and certification services | You would rather not run the testing yourself and want certification handled for you |
Where it is used
- Setting up Level 3 verification for a new development
- Regression after a configuration change or update
- Coverage checks ahead of certification
Relationship to certification
Testing uses the test suites qualified by the scheme. The approval itself is issued by the scheme or the acquirer.
