The tests (LFA strips that basically work like pregnancy strips) were first developed back in February and have been modeled to be accurate enough with daily (and up to 3 day) testing to stop transmission in its tracks. Development has been slow on rapid tests since the FDA seems to not understand tests primarily for surveillance shouldn’t need to meet guidelines for diagnostic testing. For those interested in reading the preprint on the modeling: Larremore, Daniel B, Bryan Wilder, Evan Lester, Soraya Shehata, James M Burke, James A Hay, Milind Tambe, Michael J Mina, and Roy Parker. “Test Sensitivity Is Secondary to Frequency and Turnaround Time for COVID-19 Surveillance.” Preprint.

For nasal/saliva antigen point of need rapid tests, there are at least 4 different kinds being sold commercially outside of the US currently. The Indian MyLab Pathocatch is $6/test.
