Here’s how government is making it easy to know whether someone is vaccinated or not – Times of India

In order to make it easy for airlines, railways, hotels and others including your office to know whether or not someone is vaccinated or not, the Ministry of Health and Family Welfare has introduced a new CoWIN KYC API that will tell the vaccination status of a particular person without revealing his or her personal details. With this system, airlines, hotel, railways and any one using the API will automatically get to know the vaccination status of passengers or customers.
To use this CoWIN API, an individual needs to enter his/her mobile number and name. Thereafter, they will get an OTP which they have to enter. In return, Co-WIN will send a response to the verifying entity on the individual’s status of vaccination.
The response will be presented as 0,1 or 2. This translates to: 0 – Person is not vaccinated, 1 – Person is partially vaccinated, 2 – Person is fully vaccinated.
This response will be digitally signed and can be shared instantly with the verifying entity. “A real-life example could be when at the time of booking a railway ticket, an individual will input the necessary details for buying the ticket and if required, the concerned entity will also get the vaccination status in the same transaction, with the due consent of the individual,” as per a statement to the media.
KYC-VS will facilitate all such use cases and more. It is both consent-based and privacy preserving. Also, in order to facilitate quick integration and faster adoption, the Co-WIN Team has prepared a webpage with the API, which may be embedded in any system. The service may be utilized by any service provider, private or public, for whom verifying an individual’s vaccination status is critical for facilitating a service requested.
With this API, an enterprise or employer may get to know the vaccination status of its employees to resume functions in offices, workplaces etc. Also, hotels can get to know the vaccination status of the residents at the time they are checking into the hotel, or at the time of making online bookings.
