Technological advancements can constantly be seen as both startups and established companies try to figure out the best approach to the future. But how feasible are some of the options out there that may appear, and how do they compare with more traditional card processing software?

British website The Grocer described a study conducted in France in which shoppers used their fingerprint instead of the usual stripe on plastic. While the product did require consumers to have a card in their name, the actual payment process involved them placing a finger into a scanning device. Though most of the subjects tried seemed enthusiastic about this mode of payment, others are skeptical about different kinds of biometric feedback.

For example, there's the recent Gizmodo piece in which author Adam Clark Estes examines the possibility of a facial recognition payment system for actual feasibility in the near future. In his estimation, there are some notable drawbacks.

"On one hand, the pay-by-face method is fast and entirely effortless," Estes writes. "Again, there's no need wave your smartphone at anything. But even that benefit is tenuous, since 1) you're going to need to carry around a debit card or cash for everywhere without a face-reading kiosk, and 2) is the 5-second transaction (assuming it goes smoothly) really do much for you over a 15-second swipe-and-PIN purchase?"

No matter what happens in the future, payment processing software can help keep a business properly equipped for the consumer demands of the here and now. Stores can avoid the controversy that could come from implementing these less familiar systems too early.
