As the process currently works, customer registers and rents a car at the rent-a-car booking site. She then travels to the destination airport, finds the rental agency check-in counter, and shares her identity documents and drivers license, after which the agent prepares a car rental and insurance contracts (and some other paperwork), which she then signs.
She then goes to the car parking depot where she usually again shows rental contract or confirmation to another person (car issuing agent), who then issues her the car keys.
With Identyum Web API integrated into a car booking site, customer verifies her ID document and drivers license even before she leaves for a trip. In addition, she’s issued an advanced signing certificate, which she then uses to sign rental and insurance contracts in a legally valid way. The car booking confirmation is attached to her identity.
This way, once she arrives at the destination airport, she can skip the rental check-in desk altogether. She can simply go to the car depot, tap her smartphone to the NFC tag there (or scan QR code) and then authenticate herself on her smartphone, to prove that she has a valid rental contract for a specific car. The agent then just prepares the car and issues her the car keys.
