The SCRA DynaFamily Programmer's Manual is the complete reference for the Multi-Interface Card Reader Platform (MMS) command set. It's written once for the whole family — DynaFlex, DynaProx, and DynaFlex II Go share the same commands, responses, and notifications — so this manual is device-agnostic. To confirm which commands a specific reader supports, use the DynaFamily Command Matrix.
New to the platform? Start with About The SCRA DynaFamily Programmer's Manual for scope and conventions, and About Terminology for the vocabulary used throughout.
