Multicurrency digital payment system: Fundamentals of technological support

The symbolic model (s-model) of the normalized multicurrency digital payment (NMDP) system is considered as a component of the s-model of the normalized economic mechanism (NEM). The technologies of the NMDP-system relate to the technologies of commodity-money circulation of NEM. The core of the s-model of the NMDP-system is represented by situationally changeable mandatory and orienting requirements for the properties and functioning of the system. The participants of the NMDP-system are identified by individual tax numbers and computer devices registered in the system for online interaction when making payments. At each time interval, the sets of acceptable trade transactions, the currencies used for settlements, and the rules of trade fees are defined. The NCSP-payment can be made in any currency from the list which is the intersection of currencies sets allowed by central banks of the states to which the participants in the trade transaction belong.
