Offline tests use previously captured images as inputs to core biometric implementations. Such tests are repeatable and can readily be scaled to very large populations and large numbers of competing products. They institute a level-playing field and produce robust estimates of the core biometric power of an algorithm. This style of testing is particularly suited to interoperability testing of a fingerprint template (see [ISOSWAP]).
