1. A modular entry system capable of conducting a device-to-device communication transaction with a wireless user device, comprising:
a main logic controller;
a card reader electrically coupled to the main logic controller and configured to conduct a secure communication transaction with the user device, wherein:
a first communication from the card reader to the user device occurs over a first communication path and includes the card reader broadcasting a unique device ID;
in response to the user device detecting the first communication, a second communication from the card reader to the user device is initiated and occurs over a second communication path, wherein a NFC tag having a unique set of identification data comprising a nonce is communicated to the user device; and
in response to the user device receiving the nonce, a third communication from the user device to the card reader occurs over a third communication path, wherein:
the user device sends an encrypted message comprising an access request to the card reader using the received nonce; and
the third communication path comprises a different wireless protocol than the second communication path.
