People who use contactless payment cards like them, but a majority remain unfamiliar with the technology, according to a report released Wednesday by the Smart Card Alliance.

The Princeton Junction, N.J., trade group said that 92% of consumers with contactless cards consider them fast and easy to use, and that 85% of cashiers know how to accept them.

The alliance surveyed 1,500 adult Internet users and 500 users of contactless cards. Only 25% in the group of 1,500 were familiar with the technology, though that was an improvement over the 15% in 2006.

Even in ZIP codes where the cards have high levels of penetration, nearly half of consumers surveyed said they were not familiar with contactless payment cards.

"Building awareness of contactless benefits to get consumers to try it is critical," Randy Vanderhoof, the trade group's executive director, said in a press release.
