All well and good the home test, but it opens up room for error - airlines / government aren't necessarily going to believe a test you did at home. Stringent controls will be in place - such as tests done by a qualified nurse/medical practitioner. Home testing will come later for NanoDX they are focusing on the big prize first.
Some earlier announcements in BioWorld will give you some background in this:

NanoDx have partnerships "Nanodx said that it already has partnered to get the SARS-CoV-2 test system to various outlets – such as airlines and sports leagues – that could use the device,which is about the size of a toaster. People could be assessed prior to participation in such characteristically crowded activities".

CDC director says COVID-19 tests for US flights could ease spread
The director of the Centres of Disease Control and Prevention suggested that testing people for the coronavirus before US domesticflights could help reduce transmission, as she urged state and local leaders to maintain steps to limit COVID-19’s spread.
Requiring travellers to receive a negative coronavirus test before boarding domestic flights could be “another mitigation measure,” CDC Director Rochelle Walensky said during a press briefing. She didn’t say whether the CDC will move forward with the policy, which the Biden administration is actively considering.
Transportation Secretary Pete Buttigieg told Axios the discussion is ongoing and the decision will be “guided by data, by science,by medicine, and by the input of the people who are actually going to have to carry this out.”
Walensky’s comments came as federal health officials watch for more evidence that a variant of the coronavirus wide spreadin the UK will become the dominant strain in the US.
Anthony Fauci, director of the US National Institute of Allergy and Infectious Diseases, said that could happen by the end of March.
So far, 699 variant cases have been identified, 690of which are the UK strain. Walensky said the US expects to at least triple its sequencing in the next several weeks, giving it a better snapshot of how widely the variants may have already spread on US soil.
“Once we have more sequencing that’s happening,we’ll have a better idea as to how many variants there are and what proportion are out there,” she said.
Quick number crunch for Airport sales potential looking at old FAA and EU Data:
FAA(2019) data 2.9m people flying daily in the US.
EU (2019) data 2.846m people flying daily within EU.
Let’s say the NanoDX cartridge testfor Covid19 gets very competitive down to say $5 a test.
USA That would be $14.5mper day – $5.29b yearly.
EU That would be $14.23m per day - $5.193b yearly.
Obviously Sensera has a MEM sensor in every cartridge - not sure how much Sensera will get out of each sale. But it all looks positive. 
Ellume test kits are $30 a test. Maybe the above in theory price of $5 is conservative.
The above are my own personal opinions and thoughts - do your own homework before investing.
