POS Application Development - Point of Sales app

About PayNow

PayNow is the minimalistic point of sales app, allowing its customers to collect and accept payment on their phone. It is available on both Android and iOS platform and uses stripe for processing the payment. The app targets small vendors, service providers, food delivery vendors and other such vendors and enables them to collect payment from their customers directly using the card.

How did our client get the idea?

Our client has a background of software development and she figured-out a gap while making a payment whenever any customer does not have the cash to pay for the bill. She thought there could be an easy way to solve this problem and came to us.

How did our client approach us?

As she has already worked with us for her 2 to 3 projects and was pretty impressed with the service that we provided, so she directly came to us with the problem. She described the entire problem to us.

What was the proposed solution?

We built a mobile payment app that detects credit card details using NFC or camera and processes the payment using Stripe for secure transaction.

In short, PayNow, mobile payment collection app, helps vendors to accept payments from their customers without paying higher fees.

Were there any technical challenges?

According to client’s requirement, the client was charging a 10% commission on each transaction that was happening on the platform. At that time, stripe did not support dividing payment into two and transferring the money into different accounts.

To solve the above-stated challenge, we contacted stripe customer support and described them our situation. After that, they helped us by providing support and necessary APIs to achieve the goal.

Key features of PayNow App

Quick and easy way to take card payment

Supports NFC tap payment

Simply tap any card with the PayWave/PayPass logo to the back of your NFC capable device until it beeps and your card details will be filled automatically.

App Development of PayNow Application

Our client had an experience of working with us, so we immediately started working on the project. We started working on the Android app for POC and assigned one Android engineer with more than 4 years of experience in the Android app development industry.

However, our developer spent some time researching on how to integrate NFC, Stripe SDK and Camera features in a way that is feasible and scalable for future enhancements. Once the Android app was successfully completed, we delivered it to our client for her approval.

After her approval, we started working on the iOS application once POC was done by the client. We assigned one of our experienced iOS developers with 3+ years of experience in iOS app development industry. Keeping Android app as a reference point, our iPhone developer was able to deliver this credit card payment app on the iOS platform in short span of time to our client. Here’re the tools and technologies we used while developing this payment app for Android and iOS.
