Fastcompany has an article, Credit Cards Will Go Electronic, Then Disappear Into iPhone 5, predicting the merger of RFID-enabled credit cards and smart phones.
“Nokia plans to add antennas and RFID communications chips into its phones soon, and Apple has been patenting the heck out of the idea, but both companies were probably going to rely on an in-phone antenna loop. It seems increasingly certain Apple is going to bring RFID into common usage with the iPhone for 2011 (the iPhone 5) because there’s a new patent that shows just how far Apple has gone with design thinking for RFID. The patent shows how an RFID loop, powerful enough to act as both RFID tag or a tag-reader, can actually be built right into the complex layered circuitry of the iPhone (or iPod Touch) screen. We know Apple is fond of highly-polished design and integration, and this innovation is no exception. The screen has to be exposed by its very nature, which is good for RFID purposes — the wireless signal is unobstructed by other bulk in the smartphone, and it frees up Apple to do what it likes with the rest of the phone’s design.”
Maybe building RFID into smart phones will finally unleash the potential the technology offers for cool people oriented applications, as opposed to boring inventory management tasks. However, I don’t like the idea of not being able to use my credit card because my phone ran out of power.
