Abstract: Provided are methods and systems using quick response (QR) codes for facilitating social interactions using social media. The QR codes may be generated by a service provider upon request from a user and forwarded to this and/or other users. The QR codes may encode specific user information, such as user contact information, or may encode a webpage URL for directing users to a website. The website may be hosted by the service provider and contain information for a particular event, such as a guest list and currently present attendees, or information about a group. Upon receiving a QR code from the provider, a user may choose to print this code or to display it on a mobile device. The user may scan the QR code at the venue location to gain access. Other invitees associated with this event may receive notification of the user now being present at the venue.
