How the CASHMAG algorithm works

CASHMAG cash recyclers favor change back on high stock coins, saving on low stock coins, while carefully returning an acceptable amount of coins to your customer.

Example of change back

Example of a 4 € sale with a 5 € note inserted by the customer, change back amounts 1 € and the stock is:

Greedy algorithm

• With the conventional change back system, also know as « greedy mode »:

Change back will be 1 coin of:

This will be thus lower the stock of 1 € coins. This method forces the business owner to go get new 1 € coins from the bank, and bring back 0.50 € coins which are now in excess.

This method, yet simple in appearance, makes life more complicated for the owner and increases useless trips to the bank.

CASHMAG algorithm

• With CASHMAG algorithm:

The software returns change in 2 coins of:

This way, 1 € coins get spared while 0.50 € coins naturally offload.

The business owner then needs less trips to the bank. It increases his autonomy to several days or even weeks and makes his job easier.
