ABE - Carteirinha is a free Android application developed by ABE - ASSOCIACAO BRASILEIRA DOS ESTUDANTES. It falls under the category of Education & Reference and offers a digital student ID for students in Brazil.

The program aims to replace the traditional physical student ID by offering a digital version that can be accessed on the user's Android device. The app requires the user to register with their personal information and the information of the educational institution they are enrolled in. Once registered, the user can access a digital version of their student ID, which can be used to prove their student status when needed.

In addition to the digital student ID, the app also offers other features such as access to discounts and promotions offered by partner companies. The app is easy to use and offers a convenient way for students to carry their student ID with them at all times.
