Proximity Controllers & Readers

Proximity readers are a popular choice for many access control systems. But what is a proximity card reader, and why would you want one? In terms of access control, a door access reader is the first security measure people encounter when trying to enter a space. In order to gain entry with a proximity card reader, the user needs to have an authorized proximity card on their person. Proximity cards and readers use RFID (radio frequency identification) to communicate wirelessly, with authorization data encoded on the cards.
