# 3.6.2 PCL FREE PASS

Through an MOU with PCL—a Korean medical device company, FingeRate developed the PCL Free Pass with our expertise and knowhow on developing Pass\&Go. PCL Free Pass is a mobile application for COVID-19 total solution that allows its users to certify themselves with COVID-19 negative test results by using PCL COVID-19 self-diagnosis kit. Like Pass\&Go, PCL Free Pass also generates temporary digital credentials (in the form of a QR code) for those testing negative or possessing immunity.
