The invention discloses a digital-vein intelligent door lock and work flows. The digital-vein intelligent door lock comprises a digital-vein door lock main body and a circuit board, wherein the circuit board comprises a core processing module, a digital-vein module, an intelligent voice module, an audible alarm module, a touch key module, a power supply module and a display module. According to the digital-vein intelligent door lock and the work flows, a digital-vein in-vivo identification technique is adopted, the digital-vein intelligent door lock is distinguished from general fingerprint lock sets, unlocking carried out through template imitation by technological means can be effectively prevented; meanwhile, by adopting motor unlocking, the door lock disclosed by the invention is safer and more effective compared with the existing electromagnetic unlocking.
