All over the world, Касир (Kasir 
, Kathir 
, Касир 
) is quite a common largely male, but infrequently girly first name. The forename Касир is characteristic of Western Asia, particularly Oman, where it is quite a rare male name, Qatar, and United Arab Emirates. Not in comparison with a country's population, it is commonest in India, Indonesia, and Saudi Arabia. Also, Касир is the last name as well as the forename.
