This is my son's preferred way to add money to his Nintendo Switch. We order it from Amazon and then he types in the code on his Switch immediately and he's good to go. Getting the code is a bit tricky if you don't know where to look on Amazon. You have to go to Your Orders but instead of the general orders you have to click on the tab that says Digital Orders. There you'll find two sets of numbers. It's the second number you want. We've bought this 'card' in several different increments and all have been great. If you want your child to buy able to purchase games but not have your credit card linked to his/her account, this is a good way to do it.
