Payment Gateway

Key considerations for payment Gateway integration

Now, let’s have a look at the key features of payment gateways and how they must operate. 

  1. Payment options

First off, e-wallets need to offer customers payment options to pick from. Often it includes the possibility to attach credit/debit cards, PayPal, or other likewise systems.

2. Transaction fees

Additionally, transaction fees must be reasonable. Ideally, these fees will vary depending on the payment method and the overall amount of the transaction and are typically determined by the payment processor.

3. Payment processing time

Given the importance of speed in today's digitalized world, this factor should be prominently highlighted on every developer's worksheet for e-wallets. Given this, clients can confidently use your digital wallet regularly.

4. Integration with the e-wallet system

Your payment gateway needs to be compatible with e-wallet systems like PayPal and Apple Pay so that customers may use their e-wallet accounts to make purchases.

5. Security and fraud prevention

Finally, as already mentioned security must have the utmost priority as one data leak is enough to lose millions of customers.

Database Design and Management

A reliable and safe database is the backbone of any e-wallet system. Why? Because it contains all the data the app needs to function, including user accounts, financial transactions, and payment details. Therefore, it is crucial that the database is well-managed to guarantee the safety, development, and dependability of the system, and that it is also simple to use and store. 

Database Design
