Sa kanilang website, sinabi ng BSP na marapat na suriing mabuti ang mga banknotes para masigurong genuine at hindi peke ang perang gagamitin sa pamimili maging ang kanilang ibibigay.
Ayon sa BSP maaaring suriin ang pera sa pamamagitan ng “Feel-Look-Tilt” method.
Maaari itong gawin sa pamamagitan ng mga sumusunod :
Feel: Feel the paper. It is rough to the touch because of the material used and the embossed prints.
Look: The embossed prints, watermark, security fibers, asymmetric serial numbers and see-through mark on the banknotes can be seen by the naked eye.
Tilt:. The concealed value becomes visible when the banknote is rotated 45 degrees and tilted down.
The embedded security thread in the P20 and P50 can be seen from either side of the note when viewed against the light.
The windowed security thread (for higher denominations), optically variable patch (for 500- and 1000-Piso bills) and optically variable ink (for 1000-Piso bills) change color when viewed at different angles.
