This leaves Android devices as the primary vehicle for using NFC for access control. However, they are proprietary with the technology, so third-party applications cannot access the chip yet. You may have seen this tech at play in Apple’s new Apple Pay functionality-Apple has enabled its wallet feature to access the NFC chip and approved banks can enroll cards in the wallet. NFC, meaning near-field communication, is a set of regulations built over RFID tech and essentially it makes the communication quicker and more secure, while limiting it to very short distances (<1 inch) for safety and ease of communication purposes. Moreover, this RFID chip adheres to the NFC standard, meaning that all smartphones these days can operate as NFC cards. What’s interesting, though, is that this tech is not limited to access cards and readers: Most modern smartphones have an RFID chip inside them. Most modern smart access cards are NFC-enabled cards. RFID chips exist in many variations, with the most common being NFC chips. We’ve covered RFID technology at length in another article, it’s just important to remember that that RFID relies on radio waves to communicate, and the two devices in question communicate identification messages using radio waves. Both work without needing to pair the phone to the reader, meaning that you can just start using your phones as an access card with minimal onboarding! The following section will discuss these two methods and how they function.

Specifically, many phones use the NFC standard of RFID and the BLE standard of Bluetooth for such unlocks. Mobile-based access control relies on a couple of different technologies: RFID and Bluetooth.
Let’s first take a look at the tech behind mobile-based access control. With this new standard, you’d be able to use your phone as an access card, and unlock doors with the phone itself. With the increasing popularity of cloud-based applications, and the power and versatility of modern smartphones, more and more access control companies are moving toward a mobile-first model.
