Capital One, one of Isis' three founder card issuers, is pulling out of the NFC venture's pilot tests.

Notification has been sent to cardholders who have been participating in the pilots and, Capital One has told NFC World, "our pilot test with Isis will be coming to an end soon."

"We have gained valuable insights from our customers who were among the first to pay with the Isis Mobile Wallet," the card issuer added. "We continue to engage with Isis on the future of mobile payments."
