Key takeaways

  • Eliminating setup friction and implementation costs: Turning your mobile phone into a contactless payment terminal requires zero technical expertise, with minimal setup required.
  • Never miss a sale: With your smartphone doubling as a payment terminal, you're equipped to accept contactless payments anywhere — from pop-ups to peak-hour rushes.
  • Activating Tap to Pay: Apply for a KPay merchant account, and activate the Tap to Pay feature within the KPay App or KPay Dashboard to start collecting contactless payments in Cashier Mode.

Upgrading your payment systems or expanding your accepted payment methods comes with a lot of considerations for small business owners and solo entrepreneurs. When it comes to introducing new tools into an existing system that works, you may foresee challenges like high implementation costs, business downtime, or cases where employees struggle to adapt to new systems and slow down operations.

For small businesses and entrepreneurs, ensuring your payment processes are running at peak efficiency is a necessity. This is where Tap to Pay comes in – a contactless payment solution that empowers businesses to deliver the fast and secure payment experiences that your customers expect, anywhere and anytime.

Common pain points of SME payment processing

Costs of implementation

As SME business owners, the pressure is on you to maintain healthy profit margins while trying to keep prices affordable for your customers. Traditional contactless payment methods often incur maintenance costs and miscellaneous costs, such as thermal paper for receipt printing.

Workflow disruptions

For fast-growing SMEs or business owners who are always on the go, it's important to ensure a seamless process when it comes to accepting contactless payment options for a smooth customer experience. Introducing the wrong payment processing tool into your workflow may confuse staff members if they are not properly trained to use the payment tool, or trigger system downtime during crucial sales windows.

Decentralised payment histories across different platforms

At the cost of accommodating different customers' payment preferences, your payment transactions are scattered across various payment platforms every business day. Manually piecing everything together at the end of the day takes time while incurring the risk of manual accounting errors and transactions unaccounted for.
