The government had asked those having hand-written passports to get machine-readable ones having bar codes by November 24.
The government had decided to discontinue hand-written passports in accordance with recommendations of the International Civil Aviation Organisation (ICAO) to incorporate biometric data in the machine readable travel documents, reports Firstpost.
Hand-written passports became invalid for travelling abroad from November 24, said a government official.
The machine readable passports have greater protection against fraudulent practises and tampering.
The hand-written passports were issued prior to 2001.
