One of the key features of Plexly is the flexibility it offers users upon sign-up. Users can choose between a digital card, a physical card, or both, providing a level of customization that caters to diverse user preferences and needs. This choice is not fixed, as Plexly allows users to switch their preference at any time, ensuring that they can adapt their financial tools to suit their changing circumstances. This flexibility sets Plexly apart from many other finance apps that often lock users into a single option at the outset.
