How?Mobile money management takes three steps:
1) collecting credit card information from the customer;
2) tokenizing customer’s credentials;
3) sending the token to the backend server to initiate a charge.
Secondly, a digital wallet app must be totally secure and be able to ensure the protection of the customer’s credentials data.

Steps to BuildSecure and EasyMobile Payment App
1. Choose the app type you’re going to make
Let’s start
Step #1Will you sell something directly to the app users or will there be another company involved to take care of payments from your customers?
You must decide whether or not do you need plastic card scanning (mPOS system).

2. Define the approach to mobile app development
Native apps vs Hybrid
Step #2The choice is going to make an impact on the cost of your app and its effectiveness.
Native apps are up to 15 percent faster than hybrid apps, but the hybrids are cheaper to make and take less time to develop for different platforms.
To make a right decision and to find out which of these approaches is suitable for your project, you can read more about their specifics in our guide ‘How To Build A Mobile App In 7 Easy Steps’.

3. UI/UX design
Step #3The UI design should be plain and simple, ensuring that the app works fast and aren’t disturbing the users with its complicated money transfer processing or hard-to-understand details.
Make sure to use the font and colors that will work for all ages and the whole concept should be reflecting your brand’s look and feel.
And keep in mind the necessity of user engagement – you not only have to get them involved with your app, you have to make them stay in a long-term relationship.

4. Credit card data storage and handlingGateway API and SDK
Step #4
A mobile payment app allows you to store and use your debit, credit, ID, insurance memberships and loyalty cards.
It turns all that information into a barcode to be scanned by merchants. But to become a mobile payment provider of choice, you must offer the customers an attractive and simple user experience based on NFC, QR, SMS etc., that helps to build tight bonds between the brand and the consumers. Therefore, you should learn how to properly handle and store all the credentials that your users entrusting you with.

Step #4
The API call should hand back a token from your secured server. Such token represents the submitted credit card, therefore, can be used to make actual transactions.
There are well-supported mobile SDKs for that APIs that would be a good option for a startup.
You’re still responsible for the security of credit card data, even after gateway API integration.
You must not store the credit card data in your app directly. There are a large number of the specific payment gateways that are designed to process credentials transaction through their APIs.

WePay APIthat stores a credit card info securely on WePay's servers, and returns your platform a token. It can then be used to complete a transaction without any further user interaction.
Android Pay APIthat lets customers digitize and securely store your loyalty cards, gift cards, and offers in their Android Pay app. Merchants enjoy simple integration and benefit from higher conversions.

5. Security and liability & Data Protection
PCI compliance
Step #5
Becoming PCI certified startup can take months even if you’re not a newbie and your company specializes in storing and processing credentials.
But there is a sort of way out.
The gateways or popular payment systems offer robust native mobile libraries for iOS and Android and sensitively ease PCI compliance for you by transforming an encrypted credit card data into a token.
The most important is that you are now under the obligation to make a secure mobile app for payment and to get in the Payment Card Industry compliance.

6. Handling Errors
Step #6
And instead of asking them to re-enter their information or come back into app later, handle the issue as best you can, so that the users can fix the problem themselves or call their bank and pass the responsibility to its workers.
The ways to do such tech support for your customers could be a simple highlighting of the error in red or a clear and ease-to-understand explanation for any server issues to reassure the user that it’s not his/her fault if this is the case.
Sensitive errors in the mobile payment app will happen, no matter who’s fault it will be – the user’s, the bank’s, or your own server’s.
