Which of the following is an example of a Telecommunication access device?

• A. A library card
• B. A PIN code used to access a financial account
• C. A transit pass
• D. A digital photo

Answer: (B)

A telecommunication access device is a credential that lets you access a telecommunications service or network. A PIN code used to access a financial account fits this because it functions as the secret key that authenticates you to a network service online, allowing you to enter, authorize transactions, and communicate with the service over the network. The other items don’t serve as credentials to access telecom services: a library card opens library resources, not a telecom network; a transit pass controls access to transportation services; a digital photo is data, not a means of authenticating to a network.
