How this Aadhaar Offline Paperless eKYC document is different from the other identification documents produced offline by residents?
Identity verification can simply be accomplished by providing an identity document like PAN card, Passport etc to the service provider. However, all these documents, which may be used for identification can still be forged and faked which may or may not be possible to verify offline instantaneously. The document verifier has no technological means to verify the authenticity of the document or the information it contains and has to trust the document producer. Whereas, the XML file generated by the Aadhaar number holder using Aadhaar Paperless Offline e-KYC is digitally signed document using UIDAI digital signature. Thus, the service provider can verify the demographic contents of the file and certify it to be authentic when doing the offline verification
