Described herein is a system and universal access control device that may be installed in proximity to, or within, an access control system to enable a user to use a user device to gain access to a secure area or resource. In some embodiments, a user may submit a request for access to a remote server and may be provided with an access token. The user may relay the received access token to the universal access device via a wireless transmission means on his or her user device. The universal access device may verify the authenticity of the access token by relaying the access token information to the remote server. Once the access token has been authenticated, the universal access control device may retrieve a credential stored in memory and provide that credential to the access control system to enable the user to gain entry to a secure area.
