Security Token
A security token is an investment vehicle which has the character of a security, i.e. it is bought in anticipation of future profits in form of dividends, revenue share, or price appreciation.
A security token is a peripheral device used to gain access to an electronically restricted resource. The token is used in addition to or in place of a password. It acts like an electronic key to access something. Examples of security tokens include wireless keycards used to open locked doors, or in the case of a customer trying to access their bank account online, bank-provided tokens can prove that the customer is who they claim to be.
Some security tokens may store cryptographic keys that may be used to generate a digital signature, or biometric data, such as fingerprint details. Some may also store passwords. Some designs incorporate tamper resistant packaging, while others may include small keypads to allow entry of a PIN or a simple button to start a generating routine with some display capability to show a generated key number. Connected tokens utilize a variety of interfaces including USB, near-field communication (NFC), radio-frequency identification (RFID), or Bluetooth. Some tokens have an audio capability designed for vision-impaired people.
