New Delhi: CoWIN has developed a new API called ‘Know Your Customer’s/Client’s Vaccination Status’ (KYC-VS), which will enable a verifying entity to know whether a person has been vaccinated against COVID or not, the Union Health Ministry said on Friday.
To use this 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, CoWIN will send a response to the verifying entity on the individual’s status of vaccination, which will be as follows:
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.
To provide proof of vaccination for each of these individuals, CoWIN is already issuing a digitally verifiable certificate.
This certificate can be saved on a digital device (smartphone, tablet, laptop, etc.) or stored in Digi Locker from where it can be digitally shared as and when required as proof of vaccination, the ministry said in a statement.
Similarly, at entry points where such certificate is required (e.g., in malls, office complexes, public events, etc.), it may be shown in both digital and physical forms.
