Digging more into RxScanner:
As far as I can tell, 100% of the information out there about its claimed efficacy comes from the manufacturer itself, with zero independent studies. Innovations for Poverty Action (IPA) Nigeria+ USAID + Bloom Public Health initiated a RCT that was supposed to be evaluating it against lab tests with results to be published in April 2025, but as far as I can tell, the results were never published.
From a technological perspective, if it is what it says at all, one would expect that it could be pretty good at confirming something as genuine and in pristine condition but pretty bad at telling if something is counterfeit. E.g. a generic of the same drug, or a slight formulation change (such as the binder or coatings), or some meaningless degradation during storage, will give a different result. Sounds like they're trying to bypass this by using AI to tell what differences are meaningful or not. But without third party validation.... *shrug*
Also, the manufacturer initially marketed itself as a hardware and SaaS company, but has now been broadening out, making e.g. a B2B marketplace where the sell drugs to pharmacies (RxDelivered) and a financing and point-of-sale software service for those pharmacies (RxPay). So as far as supply chain auditing goes, i's a red flag when the "independent" quality tester also operates the marketplace selling the goods (something that they try to spin as a "trusted network"). Because they obviously benefit from any biases to detect their goods as legit but flag competitors as fake.
As it stands, I don't think one can say it's an outright grift, but on the other hand, I wouldn't put too much trust in this company as it stands.
