Abstract: Devices, systems, and methods are provided for transitioning or otherwise updating access control devices are provided. In particular, a design for a reader mounting bracket is provided. The reader mounting bracket is capable of mounting multiple data input or technology units, such as a keypad and a magnetic stripe, in various orientations. The reader mounting bracket may include a feature activator that is symmetrical about two-axes. Because the technology units can be mounted in different relative orientations, models having different orientations do not need to be developed, manufactured or stocked. The mounting bracket also provides a way to implement and flexibly orient two-factor authentication access control.
