The Taka is the official currency of India, speakers of Bengali and Assamese also use the term taka to refer to the Indian Rupee, much like the word 'buck' (pl. 'bucks') in English is used to refer to dollar amounts.
Denominations
At Present there are 8 different denominations of Taka: 1, 2, 5, 10, 20, 50, 100 and 500 taka. In late 90's, the Government issued polymer based 10 taka notes as an experiment. However, these notes were not popular and were withdrawn later. At present, the 1 taka notes are gradually being replaced with coins.
