Whenever you're on a first date with someone, you have to know the person across from you is passing some judgment, even if it's subconsciously. While you probably assume they're judging your appearance, your personality, your ability to hold a conversation, and maybe even what you're wearing, your date may actually be looking at another factor that you never even considered. A new Oct. 2020 survey has found that a large portion of men judge their dates based on their credit card. To see what men are looking for when they check out their date's card, read on.

But men were much more preoccupied with the plastic than women: 45 percent of men admitted to judging their dates based on their credit card, while only 16 percent of women said the same.What are men trying to decipher by checking out your card? Many of the men surveyed said that a miles-based or travel credit card would positively influence their opinion of their date. "A credit card with flyer miles, for example, says [they are] a frequent traveler," says financial planning expert Steven Orlowski. "This may be a good thing if you're also an avid traveler, but it may also mean [they] may be away for long stretches of time. If [they have] a rewards card, then it may suggest [they're] highly strategic with her spending."Men could also be trying to size up their date's financial status. They "want to get a peek at their date's credit card because they believe it provides a glimpse into their date's spending habits," says Orlowski. He points out that this information could be useful if the date "happens to be the one, how [he] or she spends money is going to matter a great deal in the relationship."RELATED: For more up-to-date information, sign up for our daily newsletter.So, the next time you spot a guy eyeing your payment method at the end of a date, just know they might be trying to size you up.
