“In our production plant in the forests of Sweden, we have invented a new, fully automated way to manufacture USB-keys.
With a cycle time of just under 40 seconds, five YubiKeys are finished, tested and packed in trays. This equals 450 YubiKeys per hour or about 10,000 keys per day per machine. Operator intervention is only needed when packed trays are to be replaced or trays of circuit boards are inserted.”
