What will be the cost of POS terminal for merchants,will they pay some fixed fee,or it will be monthly?
I would expect it to be a monthly fee version for easier payment options.
I aslo think that, companies are paying a monthly fee on POS devices, they are renting them from bank.
That's how it works today in business. You pay every month for use and give 2-4% of the turnover of a visa or mastercard for transactions and security. If in this case everything will be even more expensive for business, then the project will not work even for those who want to jump off the needles of traditional banks and companies.
