CHV vs. PIN
I've been rolling this around in my head for a while
Which is technically the more correct term when you're talking about a SIM card? Or are they interchangeable?
I seem to remember when leafing through the GSM standards documents regarding SIM cards they favour the term CHV?
"CHV" = Card-Holder Verification, a feature that is supported by a SIM. CHF *is* more descriptive of the function than "PIN," Personal Identification Number.
"SIM" = Subscriber Identity Module. To call them "SIM cards" is a redundnacy. Don't fret, though, we all do it from time to time.
