In most places you visit in Argentina, you will be able to use your credit or debit card. In Argentina, the banking system does not reach all corners despite the fact that it is an obligation for each business. But if you visit a small town or a neighborhood store, they may be using a virtual wallet that has cards from some countries blocked. For this reason, our recommendation is that you always have a little money with you. In any case, you will always have an ATM available where you can get more if you need.
