The Smart Case ID provides the information about the Package to all the PPP Service Providers who handle it.

Specifically it gives information about the kind of case it is and the size of case.

It also contains a unique code so there can be up to 2.8 trillion smart cases, enough for 37 thousand cases per person alive.  If we ever run out of unique case IDs we could:

  • Retire cases which have been unused for a set length of time.
  • "Retire" cases once they are too old or broken or lost.  
  • Use one of the reserved bits to give us another 2.8 trillion unique IDs.
