Nearly all new payments technologies strive to become as ubiquitous — and as secure — as possible. It's a goal that is harder than ever to achieve.
For years, this was a pretty cut-and-dried proposition. Cash, paper checks or payment cards were the go-to payment vehicles. But today's overwhelming mix of smartphone apps, virtual assistants and internet of things devices makes it harder than ever to ensure that a single payment instrument can work everywhere a consumer needs it to.
This complexity makes it difficult to predict what the next big thing may be in payments, especially because many of the ideas are competing as much with each other as they are with the older options they aim to replace.
