Report: Apple testing RFID swipe support in iPhone prototypes

Prince McLean, AppleInsider

A site focused on Near Field Communications has reported that Apple has built new iPhone prototypes with hardware support for sensing RFID chips.

Report: Apple testing RFID swipe support in iPhone prototypes

RFID (Radio-Frequency IDentification) is a technology that allows a device to sense embedded chips in nearby objects without making direct contact or without using visible light like a barcode reader. Apple has already filed patents related to a mobile “ID App” capable of using an RFID sensor, a way to use RFID to sense and connect to available WiFi networks, and a touchscreen RFID tag reader.

New RFID support in future iPhones could enable a variety of “touchless” technologies, ranging from swipe payments (where users could pay for items at a checkout, vending machine, or toll booth by swiping their phone near a payment pad), to swipe sensing of information kiosks, objects, or even animals.

Very little data needs to be transmitted between the RFID chip and the device to do useful things; a payment would only need to present the user’s account number. A kiosk could simply transmit a URL to allow users to swipe their phone to open up a web page about the local area, with transit information and maps or details on items in a museum display.

The cost of RFID chips is now down to just a few cents each in quantity, making it possible to apply them to a wide variety of uses. Shipping companies and retailers already use RFIDs to track packages much like barcodes; libraries use them to track books, farmers use them to identify animals in herds, and the army, theme parks and schools attach RFIDs to people.

RDIF in mobile applications

In Japan, QR Code barcodes have long been a popular way to obtain information about an object using a cellphone with a barcode reader or camera that can read them. Mobile phones and credit cards with RFID swipe features (like Sony’s FeliCA) have also been in use for years in Asia and Europe, and are just recently entering the US.

Apple could leverage its micropayment system in iTunes, which already has a hundred million users’ accounts with credit cards in 23 countries, to set up a payment system tied into the iPhone and iPod touch. However, simply offering a way to read RFID tags would open up the device to a variety of industrial applications where swipe sensing could be used to track inventory and discover items in the area.

Adding support for an RFID reader is apparently easy and cost effective, and can be built right into the screen according to a recent Apple patent, which stated:

“The efficient incorporation of RFID circuitry within touch sensor panel circuitry is disclosed. The RFID antenna can be placed in the touch sensor panel, such that the touch sensor panel can now additionally function as an RFID transponder. No separate space-consuming RFID antenna is necessary. Loops (single or multiple) forming the loop antenna of the RFID circuit (for either reader or tag applications) can be formed from metal on the same layer as metal traces formed in the borders of a substrate. Forming loops from metal on the same layer as the metal traces are advantageous in that the loops can be formed during the same processing step as the metal traces, without requiring a separate metal layer.”

iPhone 3.0 already supports local discovery and networking setup via Bluetooth on all iPhone models, but Bluetooth devices are too expensive to embed in lots of devices that could use cheap RFID chips.

    A really exciting development. The problem with current smartcards is they don’t offer any feedback to their users whatsoever. You just have to trust the external equipment and bet a payment has been made, but hasn’t been made twice.

    The field that particularly interests me is public transport. I find the iPhone a very pleasant companion to make transit trips. You are in de San Jose city center and type in Google Maps “Take me to Market Street San Francisco”. And then your iPhone will tell you to take a bus line number you never heard of from a bus stop you’ve never been before in ten minutes time, on top of that it tells you what it costs and you know what…? It really works! Ten minutes later that magical announced bus physically appears.

    But the thing is, once you enter the bus you have to find yourself some rumpled one dollar notes to pay the trip and no chance the bus driver can get you any change if you happen not to have the correct amount of money. So if iPhone could make the payment as well, I think that would fit in nicely.

    I’m not clear; is this about the ability of iPhone to read the RFID tags, or to transmit RFID codes? Or both??!?

    This sounds very cool…except for the security implications. People (and by “people” I mean “Americans”) are already paranoid about the RDIF tags in the new passports, going so far as to microwave them or whack the embedded chip with hammer. I’m fairly certain that these methods would not be effective for a phone.

    Therefore, I think this is great as long as a) it can be disabled, and b) uses DVDJon-proof security.

    I have no doubt in my mind that Apple has a few engineers playing with this prototype. This does not mean it will come to market anytime soon. At this point, at best, it is just a conceptual toy for the engineers. Though it is certainly quite interesting, and would be a great leap for Apple to open up a brand new market.

    (PS. Did someone once say something about Apple having the Credit Card info for 100,000,000 customers?)

    If the USPTO issues these patents, they are fools. The law says that the use has to be novel, there is no novelty in this application.

    But there is profit. And the USPTO does show a wish to keep the large companies happy.
