Unlocking doorways with playing cards is a handy and safe technique to management entry to buildings and rooms. Card readers are digital units that use radio frequency identification (RFID) or magnetic stripe know-how to learn the information on a card. When the cardboard is offered to the reader, the reader sends the information to a pc, which then grants or denies entry based mostly on the cardholder’s permissions.
Card readers are sometimes used at the side of different safety measures, comparable to door locks, cameras, and movement sensors. This helps to make sure that solely licensed personnel can enter a constructing or room. Card readers will also be used to trace worker attendance and motion, and to generate stories on who has accessed a selected space.
