NTT DoCoMo Debuts Credit Card Phone

Posted by samzenpus on from the my-phone-is-maxed-out dept.

Scott S. writes "NTT DoCoMo Unveils its new phone allowing a simply wave to pay for items at the supermarket, rent movies, get airplane tickets and more. The i-mode FeliCa serves as a "mobile wallet" that detects weak electronic signals from a reader/writer and can be used when the phone is off. Credit card phones have been an idea in the past and leave it to the Japanese to make one."

    I live in Japan and these phones have been out for atleast 5 months. That said, I use one and it's really handy. Riding the trains is very nice since I don't have to wait in line to buy tickets any more. Untill the tech. is adopted in more convenience stores outside of the train stations though, I'll still need my change purse.

    As we all know, the japanese love to use cash anyway, so I feel like a tech like this stands a better chance at becomming really really popular in the US or Europe, where credit cards are more commonly accepted. Pretty frequent to have busniess associates of mine get into jams at nice resturants because they don't have enough cash.

      I'll answer this.

      If you want to become a FeLiCa-enabled vendor, you must lease your reader directly from DoCoMo. All charges are stamped with a vendor-ID and the reader serial#. In order to get both items of information, a hacker would have to steal the reader from a store, crack it open to get the serial#, and replace the reader without causing any damage.

      If the reader is missing, the vendor is required by contract (strict!) to contact DoCoMo immediately and have that reader decomissioned. The vendor is then liable for the cost of replacing the missing reader, discouraging them from lax physical security in the first place. If the reader is returned to the store in damaged condition such that the tamper-proof seal is broken (which self-reports to DoCoMo), then the machine is decomissioned and all transactions using that serial# are investigated.

      Essentially, you would have to be a DoCoMo employee to pull off something like this successfully.

      Also, the charge always requires a button-press acceptance on the user's part to acknowledge the transaction. If someone were to just wave the reader at your phone, it wouldn't do anything unless you accept the charge (in 30 seconds or so before the transaction times out).
