Guides and references for every simulator, tool and service in ISO8583Studio.
Simulator Guides
One guide per simulator — configuration, runtime tabs and protocol details. Or start from the all-simulators overview.
Acquirer & issuer host responses — Server, Client or Proxy over TCP/IP, REST, RS232 and dial-up.
Open guide →Thales payShield 10K emulation — host commands, LMK storage, keys, PIN and MAC.
Open guide →Host-command client for Thales, Futurex, Luna, Utimaco and nCipher — console, scenarios, load tests.
Open guide →A configurable point-of-sale terminal — hardware, EMV & contactless — driving ISO 8583 to a host.
Open guide →EMV smart-card sessions — APDU exchange, TLV parsing, flow analysis and test plans.
Open guide →BIN routing, protocol translation and stand-in between acquirers and issuers.
Open guide →Issuer-side authorization — PIN and ARQC verification, limits, 0210 decisioning.
Open guide →Cash withdrawal, balance and PIN-change flows with NDC/DDC device states.
Open guide →Electronic cash register driving sale, void and refund to a payment terminal.
