Testing From Trenches, Update My Credit Card Number — Tentamen Software Testing Blog


This is a story of updating my credit card number at five Internet services where I use the feature of the recurring payment.

The Problem

Last year, my bank changed the owner. The business process of the new owner is that all customers have to replace still valid credit cards with a new one. A new card means a new credit card number. As my old card was still valid, I postponed activating a new card. Here is why.

Side Problem

I have a card from the image above. Do you notice what is the problem of that card? First, there is no credit card number. Second, the credit card number is in white numbers and it goes just a little below W and E letters. At least two letters are above the compass white circle. The result is that it is almost impossible to read two credit card numbers.
