Dimecoin is a Proof-of-Work (PoW) cryptocurrency designed to be used as as point of sale payment solution. It is currently being used in stores in the United States, Australia, and several other countries. The company is developing a mobile point of sale device that will be available on iOS and Android.

Pundi X is a blockchain based point-of-sale system that allows merchants to accept cryptocurrency. Customers use Pundi X's hardware device (XPOS) to pay like they would with cash or credit card, and merchants are immediately paid in fiat currency.
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.
