100 Rand With Omron rings

The Omron rings — a pattern of small concentric circles embedded in the note's design — are a counterfeit deterrent aimed at reprographic equipment rather than the human eye. Most modern photocopiers and scanners are programmed to detect this pattern and refuse to reproduce the image, a technology developed by Omron Corporation and quietly adopted by numerous central banks. Their presence as a named distinguishing feature on this Pick 141 variant suggests the pattern was added or made more prominent relative to the standard issue, enough to warrant a separate catalog listing.

Kganyago succeeded Gill Marcus as SARB Governor in November 2014, making his signature notes among the first issued under the post-Mandela-era iconographic shift to the Big Five wildlife series.
