Then, you have to specify if you want that your token will be credited with priority and payed transaction or normal transaction.
The payed and faster transaction is called "Account" , while the slower transaction is called "File".
In few words, if you will write the word "File" you won't pay your transaction but it will be slower to be accredited to your wallet.
