The keypad has been a fixture of the access control world for a long time. The first pushbutton combination lock is credited to Alfred A. Peters in 1875. And since then, they have been a popular — and often a more affordable — option for securing doors when a customer doesn’t want to keep track of keys or cards.
Like any technology in today’s digital world, however, the access control keypad has evolved with the times and is hardly sitting around waiting to be obsoleted by futuristic technologies such as biometrics or mobile credentials. From a growing use in residential and multi-family dwellings, to an introduction of more aesthetic designs, new form factors and multi-functionality, the keypad can be the best fit for a variety of applications.
