Make it easy for participants to periodically authenticate.The Authentication application is one way to authenticate so that retirees have the convenience of taking pension money, if retirees have problems related to using smartphone devices for authentication, retirees can still come directly to the Bank or Pos Pay Partners.In this authentication, you will be asked to imitate 3 movements to be shuffled. If it fails, it will be asked to repeat 2 times.The purpose of building this application is as an alternative to the authentication process for retirees so that retirees can authenticate anywhere and anytime via a smartphone.This application is intended for all retirees and will be more optimally used by retirees who have just entered retirement.
