Unlocking doorways with playing cards is a handy and safe option to management entry to buildings and rooms. Card readers are digital units that use radio frequency identification (RFID) or magnetic stripe expertise to learn the information on a card. When the cardboard is introduced to the reader, the reader sends the information to a pc, which then grants or denies entry primarily based on the cardholder’s permissions.
Card readers are sometimes used along side different safety measures, equivalent 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.
