We’re still some time away from iPhoners being able to tap cellies onto payment pads and walk off with purchases, though rumors and analysts and job postings all say that won’t be for long. The lack of an NFC-equipped iPhone isn’t stopping Visa from launching its Visa Mobile application for trials in Europe, which for now requires an external attachment, the (somewhat aged) iCarte accessory from Wireless Dynamics. With the app and the dongle users can start trying out phoney payments at various NFC-enabled terminals in Europe, presumably ahead of the release of a proper NFC-supporting iPhone sometime in the coming months. For now, though, is adding an extra inch to your handset more convenient than fumbling for a credit card? We’ll let our European readers make that call.
