Public authentication
Clear windows, diffractive OVDs, micro-optic motion, color-shifting inks, and tactile structures that can be checked quickly without equipment.
Q&T manufactures PolySecure® banknote substrate in Hanoi and develops next-generation embedded security architecture for central banks, state printers, and high-security currency programmes.
Vietnamese banknotes in active circulation carry substrate manufactured by Q&T. Behind every note is our dual commitment: uncompromising quality controls and continuous technological advancement.
The technical reference separates banknote security into optical, ink-based, and machine-readable controls. PolySecure is presented around that institutional model: no single feature carries the security case alone.
Clear windows, diffractive OVDs, micro-optic motion, color-shifting inks, and tactile structures that can be checked quickly without equipment.
UV fluorescence, magnified microtext, thermal response, and tool-assisted checks for banks, retailers, and cash-processing teams.
IR signatures, magnetic response, spectral behavior, and restricted taggants designed for sorters, ATMs, central banks, and forensic review.
Holograms, diffractive OVDs/DOVIDs, micro-optic movement, and micro-mirror effects form the overt layer that the public can recognize.
OVI, UV/IR, thermochromic, solvent-reactive, iridescent, and dynamic magnetic inks add independent chemical and optical barriers.
IR-absorbing, magnetic, and spectral features provide the automated authentication layer required by modern cash cycles.
PolySecure® is a multi-layer polymer substrate designed for print compatibility, transparent-window security, and verified circulation performance in sovereign banknote programmes.
EXPLORE TECHNOLOGYPolyShielded is Q&T's next-generation embedded OVD substrate architecture, placing optically variable security within the polymer structure to reduce surface-wear exposure.
EXPLORE SECURITYQ&T's facility draws electricity from Vietnam's national grid, with a closed-loop solvent recovery system designed to recover and reuse process solvents — supporting resource-efficient production.
Solvent-laden air is captured via activated carbon and 3-column distillation, then reintroduced to production. Treated air is discharged after adsorption, while captured solvent is recovered for purification and reuse.
