Tools for testing payment integrations

HCEImage develops focused tools for EMV card emulation, payment card analysis, electronic cash register simulation and protocol diagnostics in controlled test environments.

Applications

Purpose-built testing tools

Built for developers and integration engineers working with cards, terminals and electronic cash registers in controlled test environments.

HCE Test Tool

Android

Emulate Built-in, Imported or Created synthetic contactless card profiles. Import a definition or copy an existing profile, configure temporary test security overrides and reset them to profile defaults. Inspect APDU exchanges and keep local history with notes and exportable diagnostic reports.

EMV Card Analyzer

Android

An Android developer tool for inspecting supported EMV card applications, contextually decoding APDU and BER-TLV data, browsing application records and captured tags, and keeping local analysis history with notes, exportable diagnostic reports and portable traces. Clear result states and bundled offline references support controlled diagnostics; the bounded analyzer is not a payment kernel.

ECR Test Tool

Android · Desktop · In development

Simulate an electronic cash register over nexo Retailer TCP profiles. Connect to an authorized terminal or built-in Local POI, run payment and recovery operations, inspect validated XML exchanges, and save local diagnostic history and reports.
