How does credit card processing work?

If you’re paying in-store, swipe your magnetic stripe card, dip your EMV chip card, tap your contactless card, or use a digital wallet like Apple Pay. If you’re paying online, enter your credit and debit card information through the website or app. You can use a virtual terminal to process credit cards for phone orders securely.

When you provide your payment information, it is sent to the processor, who will communicate with your bank through the appropriate card networks. Your bank will approve or deny the transaction based on factors such as whether your card number is valid, if you have enough funds and other considerations.

After you’ve swiped a customer’s credit card, the approval for the charge is sent back to your payment processor. If approved, the transaction will be batched for settlement at the end of each business day. The customer’s account will then be charged, and a deposit will be made into your merchant bank account.

What Are credit card processing fees?

Credit card processing fees are the charges a merchant pays for each credit or debit card sale. Your merchant services provider sets these fees and typically includes three parts: interchange fees, assessment or service fees, and the payment processor’s markup.

Suppose you only see a convenience fee for credit card purchases, not debit card purchases. In that case, it is because debit cards have a different pricing model that usually costs less for merchants.

Manual Test Case Buying a Mobile Phone Through Credit Card

Question: Write the test cases for the given scenario. The customer wants to buy a music album and checkout with a credit card.

While answering this question, we as analysts need to make some assumptions, so I better ask the interviewer about some assumptions I am considering here. Otherwise, test cases will also vary depending on the scenarios your interviewer asked you.

• Assumption: 1.  We have to write the test cases for only the mobile application, not a web-based application.
• Assumption: 2. The customer has a Music app installed already, like Gaana, Sawan, etc. 
• Assumption: 3.  The customer has already created an account using an email ID/username and password. At this point, the user can successfully log into their account.

Test Cases Buy Music Album And Checkout With Credit Card

  If the user is already a paid subscriber, clicking the Download button should allow the user to download the album. The downloaded album should come under the download category in the user’s profile.
  II. If the user is not a paid subscriber, on clicking the Download button, the user should get redirected to the next page of “Subscription Plans and Packages” of the app.
• Buy Now/ Payment- different Modes of payment.

• Verify once the user has successfully added the card details.
  I. The user is given the option to make a payment using an existing card or by any other mode of payment.
  II. If the user chooses the option to make the payment using the existing card, verify there is an option to enter the CVV number
