Have you ever asked yourself why can't you pay for your usual morning coffee with a credit card? Credit card payments usually have variable and fixed transaction costs, which means that the merchant has to pay a bigger percentage the smaller the transaction is. This project is meant to solve the problem by basically doing payments virtually until a certain sum is reached (to have fewer transactions - hence fewer fixed transaction fees!).

A prototype system in which a group of buyers and sellers create a "pool" to save on credit/debit card transaction fees (the fixed part), thus making micro (sub-dollar) transactions feasible.

This project is written in C++, so it works in all major OSes.

A few details on the reasoning on why I made this are on WHY.MD

Keep in mind it's Google Translated for now, the Italian version is here: WHY_IT.MD

Just use gcc to compile after cloning this repo

There are many variables to customize the results

static const int N_b = 100; //Number of buyers
static const int N_s = 10;  // Number of sellers
static const int N_t = 5000;  // Number of transactions a day
static const int DAYS = INFINITY; // Number of days
static const int BUFFER = 80; // Buffer for every transaction
static const int from = 0;
static const int to = 10;

static const double FIXED = 0.1;    // Fixed cost in real money per transaction
static const double VARIABLE = 0.02; // Variable cost of transaction (in percentage)

An example of the result:

vTransactions: 	2049
Transactions: 	79
Total amount: 	10001.2
Total real amount: 	6582.84
Advantage over system: 	96.1445%
Bank balance: 	139.557
Interest rate: 	0.0212001
max spent: 	167.94
