How Can You Make A Digital Payment Mobile App?

Hello there, If you are thinking about making a mobile payment app or develop an e-wallet app then the following steps can help out you. In order to develop a wallet app like android pay first thing, you need to be having a back-end payment API ready to support payments.

Next is the app part which you also need to make. Let's come to this:

• First of all, make the 1st page to show the supported payment methods. With the help of them, anyone can pay like a Credit card, debit card, net banking.
• When you will select the payment option for example credit card, you can explore a new intent to retrieve the card details or use an accordion view to open the detail on the same page itself.
• When the user enters the card you need to check few things:
• a. Which category card belongs like domestic or international?
• b. Which is the category of cards like Visa, Amex, etc.
• Card type identification can be performed by your app and only by identifying the user input. You can set some standard prefixes for a particular card type for eg. 4 are for a visa, 50 for master, etc.
• Once you recognize the card type you can fix the length of the card as specific cards have specific card number lengths.
• After all, entering the details you have to perform 2 - level verification. one will be performed at your end and another one will on your server.
• To perform verification tasks at your end you can apply "Luhn's algorithm". This will verify whether the card details are correct or not.
• As we see in India every digital transaction should happen in 2-step verification ie. OTP verification is mandatory. So once you enter the details to your server it will return you the URL for the OTP page that requires an opening in web view so a web view should be implemented.
• Once the user fills the OTP, after verification you have to intercept the success URL and break out from web view to your final page.

So these are some essential steps that you have to remember when you are going to make an online or mobile wallet app. If you are not helping own self to develop the app then you should hire an expert and cost-effective developer. I hope that I am clear on how can you design a payment app from start to end.
