iT804F
Jin Tay
iT804F
The iT804F is an app-free fingerprint touch padlock: fingerprints are registered and deleted directly on the lock body, with no smartphone or Bluetooth connection required. It stores 10 fingerprints and pairs a zinc alloy body with a corrosion-resistant stainless steel shackle. Jin Tay has manufactured locks in Taiwan since 1980.
App-Free Operation - fingerprint management happens on the device itself, so end users never deal with apps, accounts, or Bluetooth pairing. Ideal for shared facilities and non-technical users.
Emergency Charging - a built-in Micro USB seat lets a depleted padlock draw power immediately, so a dead battery never becomes a permanent lockout.
Robust Construction - zinc alloy body with a black-nickel plated stainless steel shackle for resistance to cutting, prying, and corrosion.
Fast, Accurate Recognition - the biometric sensor is engineered for rapid matching and strict rejection of false matches; detailed performance figures are provided in the product specification sheet.
RoHS compliant materials.
Gym lockers and sports facilities, school and shared lockers, bicycle security, and backpacks or carry-on bags. Wherever keys get lost and codes get shared, a fingerprint is the credential that stays with the user.
The fingerprint padlock line was Jin Tay's first electronic product family - the starting point of the company's evolution from mechanical locks into electronic locking. Founded in Taiwan in 1980 with over 45 years of lock manufacturing expertise, Jin Tay is ISO 9001 certified and offers OEM/ODM services.
