Corona Tracing for Nursing Homes with RFID Instead of an App

Tracing apps are currently the subject of heated debates in science and politics. The function: An app uses the Bluetooth interface of a smartphone to detect other app users who are in close proximity and how close they are. If a user is verified to be infected, he or she can anonymously warn contact persons. On closer inspection, the app appears to be less practicable for nursing homes.

For the operator of a facility, the app data cannot be viewed and evaluated in case of infection. It is the responsibility of the app user to handle a warning message correctly. It is also not possible to test the function of the app.

The basic prerequisite for reliable data is that all relevant contacts have been recorded. For this purpose, residents and employees must be able to use a tracing system without technical effort and without "misuse".

Secure and Anonymous Recording of Contact Duration with UHF RFID

This is exactly where the solution "TAVI - Transponder Against Virus Infection" developed by Race Result comes into play. The system automatically records and archives contacts in neuralgic areas. Facility operators can thus reconstruct who was in the same room with whom at what time. TAVI uses UHF transponder technology. Compared to Bluetooth-based apps, the passive technology has the advantage that it works without active user intervention.

Simple Installation and Commissioning

The solution consists of track boxes, in which UHF RFID detection hardware is integrated, as well as UHF transponders for employees and residents.

The boxes are installed at neuralgic points in the facility - a hook and a power connection are the only requirements. The box registers which transponder is located when and within which range. The data is sent to a secure server via the mobile phone network.

Where several people are in contact with each other for a long time, the risk of virus transmission is particularly high. These are, for example, recreation rooms for employees and meeting rooms for residents. Here, the installation of one track box each is recommended. Positioning at other neuralgic places can also be useful, for example at the entrances and exits of individual wards or floors. The transponder is detected as it passes by.

The UHF transponders are distributed to all persons in the facility. They can be worn as stickers or lanyards. Using radio technology, they transmit an anonymous code which is received by the Track Box. The costs are less than one Euro per transponder. The transponders come in bulk on rolls and are 1.5 millimeter-thick stickers with particularly strong adhesive power. They were developed for use at sporting events. That is why they are particularly robust. The transponders are automatically detected at a distance of up to ten meters in direct line of sight.

The server stores all collected data of the track boxes with date and time. On demand, it calculates which transponders have "met" in the vicinity of the track box in a certain period of time.

The Benefits of the TAVI Solution at a Glance

For the Operator

• The system can be used quickly. Within a few days after ordering, users receive the desired hardware
• The installation of the track boxes is done by the user. No external technician has to enter the facility
• No training in software necessary
• Online support for hardware and software included
• Transponder issue to employees, residents, and visitors and can be done via a simple list, also on paper.
• No disclosure of personal data to third parties. Lists with the assignment of the anonymous transponder ID to the person remain in the facility

For Employees, Residents, and Visitors

• The only requirement is to wear the transponder
• The UHF technology used is contactless. Employees do not have to scan chip cards or keep lists
• Hygienically safe
• Transponders also work under protective equipment
• Independence from smartphones, apps, GPS reception, and battery life
