Canfield explained that mobile phone smart cards utilize an SIM (Subscriber Identity Module) card with a chip in it. "For instance, behind the battery in my phone, there is a little ID card with a 19-digit number on it that holds subscriber information. When the card is inserted, it allows the phone to authenticate through a network and identify the user. The card can be used in any enabled phone, allowing it to receive my calls and contain my phone book and all of the other applications I have on my phone. Technology that provides authentication onto a network not only simplifies billing, but it is also more convenient for users."
