Immigration entry / exit forms now a thing of the past in Abidjan airport

I just travelled through Abidjan airport and I noticed an interesting development. You no longer need to fill in entry / exit forms at Immigration. They simply scan your passport, scan your fingers and take your photo - the usual stuff. What else do you need?

I just popped over in Accra and the usual forms...

I'm amazed at why these forms are needed when all the information that's required are already available on the passport. The only additional information (on the form) is the purpose of visit and accommodation details. What relevance is this info anyway? Who's going to check if the hotel you indicated is the one that you're staying at? Most times they simply want you to enter an address, and that's it. No real interest in checking. So, what's the point?

The people who suffer the most are the illiterate travellers who are subjected to the inconvenience of finding someone to complete their forms. I see no real positive value in this old-fashioned practice, especially in a continent with high levels of illiteracy. May be someone can educate me here...
