Huge red flag for me too. Lets compare to the barcode technology. One would argue the same thing about manufacturing. "Industry where X% of Y is still done using pen and paper". In manufacturing using pen and paper means real losses when you lose items. The manufacturer problem IS losing items because of pen and paper, and they have no viable option.
In their case, people use pen and paper because it doesn't really matter. All the value is getting the people.
