Connect the chip inside the OILI to your card. See our selected payment partners and their connected payment cards and use your normal pin code. All your purchases will be registered where you normally see your card transactions. In case you would lose your OILI, you only need to block the chip in the strap and not the card itself.
When I ordered my OILI I got it home already connected to my payment card. So I could just start to use it straight away.
Rummaging through my bag to find my wallet, or forgetting it at home is simply not an option anymore!
