I am seeing “cannot read smart card”

This is showing up because the smart card for the dibo box is either not inserted, or not properly inserted. Please reseat the card.

For dibo mini - the card is inserted with the chip on the inside and the serial numbers facing you.

For dibo 3 - the card is inserted with the serial numbers on the inside and the chip facing you.

For dibo plus -  the card is inserted with the chip on the inside (up) and the serial numbers facing you (down).
