A very important reminder!
Many foreign workers who were repatriated earlier and are coming back on forged documents are being sent home by return flights on arrival in the Kingdom of Saudi Arabia. Even if they come with different passports, their identities are revealed after fingerprinting and iris scan at the airport immigration, and immediately they are sent back home.
Airlines are losing a lot of money because they have to bear the return passage of workers who are deported from the airport on arrival with forged documents. These workers do not realize that their identities are now registered in the database at the airport of the host country, and resorting to unscrupulous means would not work now.
