Barbados converted its banknote series to polymer beginning in 2022, adopting De La Rue's Safeguard substrate — the same platform used by a growing number of Caribbean central banks seeking durability gains over cotton-fibre stock in humid climates. The transparent window is integral to the substrate rather than applied separately, which distinguishes Safeguard-based notes from earlier hybrid constructions.

The TBB#242 reference places this among the earlier catalog entries for the polymer transition series, suggesting it was among the first denominations released rather than a later addition to the rollout.
