100 Dollars Polymer

Trinidad and Tobago switched its $100 note to polymer in 2019 as part of a broader regional move toward substrate modernization, but the decision carried particular urgency locally — the cotton-paper predecessor had become a well-documented target for high-quality counterfeiting, particularly in the run-up to general elections when informal cash transactions spike. De La Rue has printed Trinidad's higher denominations for decades, and the polymer contract represents a continuation of that relationship rather than any competitive shift.

The transparent window on this issue is integrated into the substrate itself, not applied as a separate patch — a distinction that matters for authentication in the field.
