Hi, I have a question.

I understand that amplitude creates a unique user profile based on three main ID values. I was wondering about the possible issues with customizing the Device ID among these.

If we customize the Device ID (because we have an NFC ticket that only we utilize), will we not be able to see the information of the mobile device (because it will not meet the device criteria)?

Or, if we customize it, will we still be collecting and storing each device separately? Just curious.
