A token is a particular smart-contract that contains a ledger. The token generally provides a way to increment the amount of its account (mint operation) and ways to transfer amounts from accounts to accounts.
The person issuing the token has full power over the token.
A blockchain account can provide functions other than making payments, for example in decentralized applications or smart contracts. In this case, the units or coins are sometimes referred to as crypto tokens (or cryptotokens).
