Honestly, pricking a finger may be obsolete
There are supposedly Covid-19 tests out there that are tabs that you lick, and it immediately tells you whether you have the virus or not.
That type of instantaneous technology is rapidly needed at the stadium and arena gates during sporting events, more than pricking a finger and waiting 15 seconds per person to be admitted in to the gate. Fans will be waiting forever outside the gate, at 15 seconds per person. Normally, they skew each ticket in less than 2 seconds per person.
How many employees at work want to have their finger pricked on the way in to work while checking in?
Now their finger is bloody, and they have to sit down and type an e-mail.
Licking a tab is so much easier and more convenient for the mass public. At work, at sporting events, etc.
99.99% of people in this world would much prefer licking a tab over getting their finger pricked.
Finger pricking is 20th century technology.
Covid-19 testing across the world will probably be 21st century equipped.
