Collecting for cleaner hands


Our UHF inlays are helping one Australian company fight COVID-19 and other illnesses by promoting proper employee handwashing in restaurants and elsewhere.

The challenge

Amid the COVID-19 pandemic, regular and thorough handwashing by staff at restaurants, bars, senior-care facilities, schools, and other public-facing businesses and facilities is more crucial than ever. But workers don’t always remember to wash their hands, or know how long to wash them thoroughly. And neither employers nor the public usually have any way of knowing if workers are practicing proper hand hygiene.

The solution

Ramp, an Australian-based system integrator, created SafeWash, a UHF-based solution that provides unprecedented visibility into employee handwashing habits and shares the data with employers and customers.



How it works

Employees enrolled by their employer in the SafeWash program wear name badges, wristbands, or lanyards embedded with a UHF RFID tag. Small sensors placed near wash basins or hand-sanitizer dispensers read the signal from the tags each time an employee approaches the handwashing station. The sensors log the amount of time each employee spends washing their hands, and a timed indicator light in the sensor illuminates for the duration of the recommended hashwashing period, to help employees know when they’ve washed enough. When the employee has finished washing, the SafeWash sensor transmits the data by WiFi to the employer and to any customer who has signed up for the program. Data is displayed in a mobile app.

The benefits

SafeWash promotes potentially life-saving hygiene and reduces the risk of disease by prompting staff to thoroughly and frequently wash their hands. By making up-to-the-minute hand-washing data publicly available, SafeWash demonstrates to customers of the business that the establishment takes hand-washing and sanitization seriously, promoting customer loyalty and bolstering its reputation.

How Avery Dennison made a difference

SafeWash employs our Belt NXP UCODE 8 UHF inlay in employee badges. The inlays contain a unique digital identifier for each employee, enabling the sensor to note and log each of the employees’ handwashing sessions. Because using UHF tags in close proximity to the human body can affect radio-frequency signal transmission, we worked with Ramp to conduct extensive testing of different inlays and badges, helping them arrive at a configuration that delivered consistently accurate readings.

COVID-19 test kits: When authenticity is king, NFC plus blockchain is the way to go

For COVID-19 control and reliable testing, authentic testing kits and personal protective equipment (PPE) are truly vital. Together with blockchain startup SUKU, Avery Dennison Smartrac developed a digital verification solution to securely authenticate healthcare equipment and provide supply chain transparency.

A wider choice for higher security product authentication

Avery Dennison Smartrac launched its NFC Pro series to empower brands and retailers to beat counterfeiting and deliver customer experiences at more secure levels - made possible through “one-time password” authentication. The new Circus™ Tamper Loop Pro inlays and tags combine these capabilities with “digital seal” tamper detection, and introduce a new IC option.

Enhancing healthcare quality with RFID innovations for the sterile goods cycle

Surgical instruments are a challenge for today’s RFID technology: made of stainless steel, they are delicate, and are sterilized at extreme temperatures (up to 121°C/250°F). Tiny, super-high frequency tags (SHF, 5.8 GHz) are needed to create a digital copy of the sterile goods cycle.
