A Multiple Badge Architectures Open Source RFID Reader with Insight Regarding Room Occupants

Abstract

The preferred architecture and the source company for radio frequency identification (RFID) badge access cards can vary over time within the same company, depending on what management may envision for the future of working. Additionally, the preferred badge architecture and the company that makes those badges can vary from company to company, and from original equipment manufacturer (OEM) to their supplier partners. These circumstances create some inefficiencies amongst the workforce. Within the same engineering campus of a large OEM, many employees may still have the old key ring style badge, but some of the new RFID device readers may no longer accept this outdated badge architecture, which means these employees may not have access to certain areas until they get their new smart badge ID card. This makes doing their job much more difficult, potentially forcing them to find new ways to access the room or area that they need. Additionally, due to differences in badge architecture, an OEM’s supplier partners do not have access to areas of the OEM’s testing site or offices, even ones in which the OEM would prefer that they have permission to access in order to increase work efficiency (including test tracks and special laboratories). This paper presents a new open sourced RFID card reader which is designed, tested and implemented to read both of the most popular badge architectures (key ring badges and smart cards). The new proposed system also includes a unique function which shows the employee more information about the occupants inside of the room that they are trying to access. After reflecting on the state-of-the-art, the main selling point of the proposed system is that it recognizes multiple different badge architectures, and it doesn’t require the end user to source their RFID devices from a certain company. It provides other benefits including allowing suppliers and OEMs to seamlessly share collaborative spaces, and ensuring older versions of badges don’t become obsolete.
