SQ1 – Mobile Payment Application Development

Challenge For Create Payment Application

To produce wearable devices more efficiently, the company needed a reliable mobile application for payment. This would allow users to link their credit cards, Flex Bands and NFC wearables and then monitor their payments. As the seamless application would be directly linked to the customer's personal information, it needed to be as secure as possible. Silk Data has extensive experience working with high-security Digital payment applications and in this case, our team understood how to fully meet the client's requirements. The team already had experience with NFC mobile payment apps for wearable devices for the Swatch company.

About the project

The Silk Data team developed a scalable payment application for iOS and Android platforms for contactless payment with a bracelet. The SQ1 FLEX mobile application makes it easy to control all Flex Band actions wherever you are.

Frequently Asked Questions

To develop payment software, begin by defining requirements, selecting a secure payment gateway, integrating with payment processors, and ensuring compliance with industry standards. Regularly update the software to address security concerns and evolving payment technologies. 

Payment applications facilitate transactions by securely transmitting payment information between the payer, payee, and financial institutions. They use encryption protocols, secure APIs, and tokenization to protect sensitive data, ensuring seamless and safe financial transactions.

The cost of building a P2P payment app varies based on features, security measures, and development complexity. Expenses include design, development, testing, security, and ongoing maintenance. Budget considerations should also account for compliance with regulatory requirements. 

Creating a payment gateway requires in-depth knowledge of payment processing, security protocols, and compliance standards. While it is technically possible to build one independently, partnering with established payment service providers can save time, resources, and ensure reliability. 

An API payment gateway acts as an intermediary between an online merchant and the payment processor, enabling seamless and secure communication. It allows developers to integrate payment functionality into their applications, providing a standardized way to process transactions and handle payment-related data.
