All of us love to ‘Shop till you drop’ but who doesn’t love to shop while earning simultaneously. No, I am not talking about your monthly salary or the profit you earn from your business but the reward that your shopping gives you. While the country goes smarter with the latest gadgets and technology, our payment also becomes smarter with digital payments coming in action. Gone are the days when you carried those bundles of notes while you hopped into a mall or made your travel booking. Now all you need are credit cards and everything is sorted whether there is money in your bank account or not. However, you need to make sure you pick the right card according to the requirements so that you can gain while you spend.
