An access control system and associated devices are described that conceal and securitize data transmissions between one or more secure databases for various user devices to ensure proper entrance or access into secure locations by approved personnel only. Specific methods and devices for securing (primarily digital and normally two-way) communications using applications that combine securing communications for wireless/cellular phones with personnel access card readers for entry into secure locations are also described. These combined communication and access devices require using specific encryption techniques that cannot be corrupted and are essential to denying fraudulent or otherwise unauthorized personnel the ability to enter or access security protected devices or locations.

It is the same self-syncing dice machine, but for your phone and the badge reader at the office. Instead of a badge that forever shouts one fixed ID number (which anyone with a scanner could copy), your phone checks your fingerprint and mints a one-time QR code that means "this user, right now, at this place," good for only a few seconds. The reader scans it, both sides confirm against their synchronized databases, and then that code is dead.
