Before checking in at any hotel, the person has to show his ID, passport, and various other documents to prove his authenticity. Thus leading to an increased check-in time.

Through Blockchain technology all the documents can be recorded on the blockchain and when a person checks in at the hotel, the verification can be done using biometrics either by face scanning or by thumbprint to ensure that he is the same person for which booking has been done. This will eliminate the need to carry proof documents and will thus also eliminate the chance of losing these precious documents.
