Create a wallet exercise

I created a wallet for Meng, for Meng she doesn’t own a wallet before she came to Parsons, and she uses her phone to pay when she was in China. When she came to Parsons she now has 2 cards, and she uses the cardholder provided by Parsons, but the issue is that she’s scared that she may lose this cardholder, in terms of color and material, she told me that she likes black and she prefers more durable material, she also said that she needs a coin wallet.

based on her requirements I came up with a cardholder design that can be attached/detached to her phone, has a detachable wallet and a ring that can be attached inside her backpack.
