Collecting name cards efficiently without losing them is a constant challenge when visiting large networking events. Currently there is no existing application that provides name card exchange without requiring any physical interaction. Existing applications only supports scanning of name cards through NFC.

Hence, BlueNet was developed to enable exchange of name cards via bluetooth as long as you are within a radius of another user. Additional features also include scanning of traditional name card and name card management. The use of bluetooth also enable us to monitor event traffic.

I was mainly in charge of the name card scanning and management feature. For name card management, I was involved in setting up our application with Firebase to store the name card data. For scanning name card, I made use of Google’s ML Kit Text Recognition API to allow reading text from images.
