Namibia's home affairs ministry has launched a biometric passport with enhanced security features.Nehemia Nghishekwa, acting permanent secretary in the ministry, launched the e-passport in Windhoek on Friday."A biometric passport is a highly secured travel document or passport with a chip for document security enhancement, rendering it difficult to forge," he said.The current machine-readable passports in circulation will still be in use until they outlive their five-year lifespan.It will be available to ordinary, diplomatic and official passport holders.Nghishekwa said the ministry will still issue the brown passport, also known as the emergency travel document, until further notice.The e-passport will cost N$160 for the time being, until government gazettes the new fee of N$200, which was approved by Cabinet last year.
