The only place anyone has to select their type of credit card (MasterCard, Visa, etc.) is in a poorly optimized online checkout. You don’t have to tell the grocery store clerk you use Visa, and you don’t have to tell many websites the same. The first few numbers in a credit card number signal this.

Still, many websites ask the user to select their card type. It’s not a daunting task, but it’s an extra step that slows the checkout process and adds perceived effort.

You reduce perceived workload and save space by doing this.


Detecting the card type is a straightforward feature to implement. The most common method is to have various credit card logos next to the card number field, and when a card type is detected, the correct logo is highlighted and the others are faded out.

The best implementations detect is as soon as the first few numbers are entered – doing this also serves as a subtle sort of positive reinforcement. It says “Hey, you’re entering a valid card, keep it up!”

As you can imagine, this is much simpler than having a user scan through a dropdown menu to select the card type.
