It may be recalled that the Bangko Sentral ng Pilipinas (BSP) has earlier issued an advisory regarding the unlawful practice of extracting the Windowed Security Thread (WST) of genuine banknotes by the fraudsters to counterfeit higher denomination, i.e., 500- and 1000-piso. This is done by pasting the extracted genuine WST on the counterfeit 500- and 1000-piso banknotes. In recent months, the BSP has observed that in order to camouflage or to cover the missing WSTon the 100-piso genuine notes, WST is simulated by using ball pen with semi-gloss ink or covering the area where the WST was removed with commercially available glossy/metallic paper.
In view of this, the public is advised to be extra vigilant to this new trick/modus operandi of counterfeiters. Genuine banknotes whose WST was willfully removed will be considered as no value, while banknotes devoid of WST but subsequently simulated or pasted with genuine WST is considered counterfeit.
In case cash handlers take hold of this type of counterfeit banknote, they are advised to surrender the same to the Currency Issue and Integrity Office through the Cash Department, Bangko Sentral ng Pilipinas (BSP), Security Plant Complex, East Avenue, Diliman, Quezon City or to the nearest BSP regional office or branch.
