"Papers, please." How could it be done without invading privacy?

• musicale 4y ago
  I'm not sure it can be easily. However, many venues were already checking ID for over 18/21 shows and also covid test results during the pandemic. Also regular buyers already have to provide contact and payment info (usually very personally identifiable.) Some venues have tried to fight scalping by requiring presentation of the card used for payment - though obviously that disadvantages cash buyers and scalpers can still use burner cards which they provide with the ticket.

  I'm not sure "privacy preserving" is enough of a selling point.

  Remove the reason why showing your papers is a privacy issue in the first place.
