Abstract: A door entry system for operating a door using a wireless transmitter device containing identification credentials of a user. The system includes a door operable by an uncoupling or releasing securing mechanism, a door controller capable of operating the uncoupling or releasing securing mechanism and a door handle for grasping by the user to operate the door, the handle having a cavity, the handle being secured to the door and spaced away from a surface thereof. The system includes a wireless device reader disposed in the handle cavity and a power source connected to the card reader. The wireless transmitter may be presented in the vicinity of the reader in the door handle and, upon verification of the credentials transmitted from the wireless transmitter device, the reader sends a signal to the door controller to uncouple or release the securing mechanism and permit the door to open.
