All you have to do is follow some steps. Download it for free on Google Play Store and Apple Store.
The first step is to sign up/log in. Here you need to provide a valid phone number, and you will receive an OTP on the same. The app is valid in India only, so only give your Indian number.
The second step is to enter the OTP. Once you receive the OTP on your phone, enter it into the app. The OTP will last for 3 min, so you better be quick. You will also be asked to read some 'Terms and Conditions' before going ahead.
This is the app's final and most significant feature. The provided medicine/injection has a scratch code. Enter the code in the app, and you will find your verified medicine/injection. You will get to know if the medicine you scanned is genuine or fake.
You can also find if someone already used that code or it's being used by someone else.
If the code is valid, a success pop-up will appear. If it's fake, then an unsuccessful pop-up will appear. The motto is to know whether the medicine or injection is authentic or not.
By following this process correctly, your medicine or insulin will get verified.
