The QR code will help the visitors of the zoos to have in seconds the complete information of the animal that you visit in your mobile phone without having to do tedious searches, just bringing your phone to the cage.
Several visitors of zoos in Mexico describe as a bad experience having to wait a long time to be able to read the information of the animals that are often stuck to the side of the cages. As people accumulate around the information thus making a bottleneck and an unpleasant experience for people who are waiting for others to finish reading to be able to approach.
This application shows how your zoo could work if there was a QR code in each of the animal cages, thus helping the zoo visitors to have the information of the animals in their hands and to avoid the accumulation of people around the information stuck in the cage.
