In order to solve the problem, the printed business card should be digitalized. Although there are several digital business card application available in the market, it does not reduce the use of hardcopy business card effectively. This project is intended to develop a mobile application for the interactive digital business card. The interactive feature of this mobile application included the dynamic content of digital business card, geo-based awareness of business card contacts’ company location with the map function, scanning function to scan and save hardcopy business cards and QR code generator for a personal business card for easy exchange. Firebase is a cloud-hosted realtime database used to sync data and perform dynamic content. Next, Google MAP API is used to produce the geo-based awareness of business card contacts’ company location with map function in this project. On the other hand, Google Mobile Vision API which provides optical character recognition (OCR) technology is used to implement the scanning function to scan hardcopy business cards and save the information extracted using text recognition. Lastly, the ZXing API will be used for decoding and generating of barcodes such as QR code for the digital business card. The project is initialized in Mar 2018 and completed in Aug 2018. The time use for the completion of the whole project is less than 6 months. All the objective of the project had been achieved. As a conclusion, the mobile application for the interactive digital business card is introduced to promote the ‘paperless office’.
