To take better care of customers and encourage them to use the services in the corporation’s ecosystem, our client built a program that allows customers to collect and spend points for any purchases or services they buy or use. Plastic cards were initially used for collecting and spending points. However, this method has shown some limitations over time, for customers usually forgot their cards at home, and it was also difficult to either check the points collected or develop new features. Therefore, they needed a mobile app that can solve all of the above problems.

  • The app allows customers to collect and spend points, as well as checking their own points collecting and spending history, at the same time automatically sending promotions and discounts notifications to customers.

Previously, users who wanted to use the service had to register for an account at a store, moreover, they could only rent DVDs at the store where they registered their membership, causing time loss and inconvenience.

  • Developed new functions that allow users to register accounts online and use this account to watch online movies as well as borrow DVDs in many different stores of the system.
  • Added new payment method according to actual usage, customers can now deposit money in advance to the account, then it will be deducted according to the services/products that they use.
