The id property of the NDEFRecord interface returns the record identifier, which is an absolute or relative URL used to identify the record.
This identifier is created by the generator of the record which is solely responsible for enforcing record identifier uniqueness. Web NFC does not sign the NFC content, thus record consumer should not make any assumptions about integrity or authenticity of the identifier or any other part of the records.
