Pundi X also has a development ecosystem that is powered by the NPXS token. Developers can create Apps that benefit merchants and customers, and can be used with Pundi X's point-of-sale system.
The company is currently developing their own blockchain that is called f(x) that is designed for everyday transactions. Each XPOS device will serve as a node on the f(x) blockchain.
