In store reps

With the recent changes regarding acknowledging biometric data when scanning driver’s license, how have you been explaining it? I mostly understand what they’re agreeing to but honestly not enough to explain it to customers without them getting suspicious about why their biometric data is being stored. I was told that we’re saving their biometrics so if they try to reset their password on t-life, it can tell if it’s really them or not… but I’m getting a lot of pushback and it’s adding an extra 10 minutes to the beginning of the transactions and I coming up short.
