Creation of a mobile application called MyBeBack designed to make stays in France more pleasant for French people living in other countries or overseas regions. When they're in France for a few days, French expatriates would like to take advantage of more attractive prices to cover their expenses. This would give them the same advantages as regular customers. Thanks to this concept, retailers will be able to reach these transient customers at the right time with appropriate offers, and above all, in an eco-responsible way.
