I carried out a test task. My job was to propose
a realistic solution for cryptocurrency (crypto) usage to pay for groceries through a mobile phone. So I designed a prototype that may become a reality someday soon.
I undertook significant research on the crypto market, and I was utterly lost as someone new to it.
The purpose of the study was to understand the significant pain points users experience using crypto today and how it is possible to implement better payments with crypto daily in future.
Crypto work using blockchain, a decentralised technology spread across many computers managing and recording transactions. Part of the appeal of this technology is its security.
While some crypto is available for purchase with U.S. dollars, others require paying with Bitcoins or another crypto.
To buy crypto, you need a "wallet" — an online app that can hold your currency. You create an account via the exchange platform, and then you can top up the account with fiat money to buy cryptos such as Bitcoin or Ethereum.
How does the user transfer crypto?
To send crypto, you'll need the recipient's wallet address. A wallet address is a long string of characters, similar to a bank account number, that identifies where the crypto should go.
Since crypto wallet addresses are long, they're often shown as a QR code you can scan via your crypto app.
Some important things to note:
So what's the problem?
I think It is only a matter of time until Facebook absorbs Binance or Apple adds crypto to Apple Wallet. And this is the scenario I decided to think through.
We believe that adding crypto to Apple Wallet for iOS users will achieve simplified crypto usage.
All the user needs to do is to double-tap the side button on their iPhone, confirm the payment with Touch ID, Face ID or password and present the phone to a card reader.
There is still a chance that the user won't have specific crypto to pay, then there is an option to add one. The user has to press the button with a 'plus' icon adding a new payment method, and select the currency. Hooray! It's successfully added. At first, the user tops up their balance to be able to pay.
There are three options in this case:
The easiest way to pay for food in the grocery store with your phone is by Apple Pay or Google Pay.
I followed Human Interface Guidelines and made the design as close to Apple's products as possible, so it would align with the Apple Wallet's interface.
