Note that some apps on our list work with multiple payment processors, while others only work with their namesake processors. If you’re just starting out, choosing an all-in-one solution is easiest. However, if you already have a merchant account or are having trouble getting approved for one, a payment app that works with multiple processors offers more flexibility.

Why I chose SwipeSimple
SwipeSimple is our top choice for credit card payment apps. It offers a wide range of in-person payment methods, including QR codes, digital wallets, and tap to pay, to name a few. The app also features invoicing, inventory and customer management, advanced tipping, and a card vault. SwipeSimple received the highest ratings from both iOS and Android users.
SwipeSimple’s best asset is its flexibility. It is used by leading merchant acquirers and payment processors like Global Payments, TSYS, Fiserv, Worldpay, National Processing, Stax, and Payment Depot. Multiple payment processors mean merchants can choose a provider with the best rates. As of September 2023, businesses can use SwipeSimple directly via a CardFlight merchant account.

Why I chose Stax
Stax is a traditional merchant account that offers wholesale subscription-based pricing ideal for mid-sized and large-volume businesses. It offers a mobile app version of Stax Pay through advanced SwipeSimple customization. Note that while Stax also uses SwipeSimple, I decided to include it separately on our list because of Stax’s versatility and customization capabilities.
Stax is a standout for the system’s ability to scale its features along with any business. This means it can provide simple payment processing solutions, but as a business grows, users can upgrade to any of Stax’s more advanced products such as high-level subscription management with Stax Bill and white label customizations with Stax Processing. The functionalities within the Stax mobile app will also upgrade along with the business needs.

Every Square merchant account receives a free magstripe reader, which can be used in conjunction with the mobile app. However, users can also manually process payments without a card reader.

Why I chose Stripe
Stripe is a payment services platform that also comes with a merchant account. It is developer-friendly payment software known for its advanced customization features. Stripe’s payment processing service also powers Lightspeed, Shopify, WooCommerce, and other popular business tools.
It wasn’t until recently that Stripe launched its native mobile app, Stripe Dashboard. The app is highly rated by both iOS and Android users, despite its limited in-person payment capabilities. That said, third-party Stripe apps are available to be used in conjunction with Stripe’s mobile card reader. For larger businesses, Stripe offers well-documented APIs and developer tools to create a mobile app customized to their needs.
What to look for in a credit card payment app
To get the most out of a credit card payment app, businesses need to consider the cost-effectiveness of each option. This helps ensure that users choose a provider that can maximize savings while also providing features they need and with room to grow.
Flexible pricing structure
As businesses grow, the priority in pricing shifts from minimal upfront costs to volume discounts. The ideal credit card payment app should support flexible pricing that will allow businesses to upgrade their services without interrupting business operations.
Variety of payment methods
The best credit card payment app should provide a full suite of in-person payment methods. This means it should be able to work with a card reader that supports swipe, EMV, and contactless payments. Hardware-free payment methods should also be available for businesses that prefer not to invest in a credit card reader for one reason or another.
Level of customization
Credit card payment apps should be equipped with a variety of customization options. This includes additional payment processing services such as invoicing, payment links, card vault, and surcharging tools. It should also provide customizations that support business growth, such as developer tools to create industry-specific features and various integrations with business systems.
Security measures
Every payment processing service should be level 1 PCI DSS compliant. Users should also look for available tokenization and encryption tools. Ideally, payment processors should also offer chargeback management and customizable fraud protection features.
App and card reader reliability
It’s important that a credit card payment app and a card reader are reliable. The best option should not disrupt business operations with bugs resulting from app updates or card readers that often get disconnected. It’s also ideal for the app to be able to process credit card payments even without an internet connection. Users should also check real-life user reviews for any complaints about frozen funds or failed transactions.
Find the right credit card payment app
The best credit card payment app will depend on a merchant’s business needs. And because not all businesses are the same, choosing the right payment app differs as sales volume size and industry change.
We recommend:
- SwipeSimple for businesses that require flexibility and want a reliable brand. It works with popular payment processors and is highly rated by real-life users.
- Stax is the best option for large-volume businesses. It provides robust payment services with native customization features and developer tools that allow the system to grow along with the business.
- New businesses will find Square’s credit card payment app the best value for money, especially for those working on a budget. Its forever-free features, which include the mobile POS app, make Square the easiest choice if you are building a business from the ground up.

- For ecommerce businesses, Shopify is the best option. Not only is it the leading ecommerce platform in the industry, Shopify also provides a POS solution (including a mobile POS app) and robust omnichannel tools.
- We also recommend Paysley for businesses that value integrations. Paysley is a popular credit card payment app used by payment processors like PaymentCloud and National Processing.
- CDGcommerce is the best credit card payment app for restaurants of all sizes. Aside from flexible pricing plans, CDGcommerce integrates with a variety of restaurant POS and works alongside the mobile app ideal for kiosks, concessionaire stands, and sit-down restaurants.
