I carry both cash and card as it's not possible to go around with either one of them. We need cash to take public transport and to buy stuff from stores that don't accept cards. These stores offer much lower prices than supermarket chains that accept debit/credit cards so they're always part of my shopping route. To stay safe, I always carry a slim belt bag under my blouse/shirt and that's where I keep my card and large bills. I only carry cash that I would need for a particular shopping trip. I also bring a coin purse where I place the loose change to pay for small purchases from market vendors. I buy meat and store brands from supermarkets and that's where I use my card.
