Excelente el análisis The ‘Credit Card Number’ Field Must Allow and Auto-Format Spaces (80% Don’t).

Typing a 15-16 long string of numbers without a single error can be challenging for most users – yet, it’s what all users have to do during the checkout flow as they reach the ‘Credit Card Number’ form field. During our large-scale checkout usability study we observed that a large sub-group of users struggle with correctly typing their 15-16 digit credit card number, and subsequently struggle with verifying that it’s typed correctly. During testing this was observed to be the direct cause for checkout abandonments as users got card validation errors due to simple typos.
