PIN Entry Device Tidak Secure

Dari CSLG, University of Cambridge:

... In Chip & PIN card transactions, customers insert their card and enter their PIN into a PIN Entry Device (PED). We have demonstrated that two popular PEDs, the Ingenico i3300 and Dione Xtreme, fail to adequately protect card details and PINs. Fraudsters, with basic technical skills, can record this information and create fake cards which may be used to withdraw cash from ATMs abroad, and even some in the UK. These failures are despite the terminals being certified secure under the Visa approval scheme, and in the case of the Ingenico, the Common Criteria system. Our results expose significant failings in the entire evaluation and certification process...

Apakah perangkat yang sama dipakai juga di outlet-outlet yang menerima pembayaran dengan kartu di Indonesia?

Batere Lagi

Dari EETimes:

... The first commercial product inspired by QuantumSphere's technology will debut later this year: a battery using a cathode coated with the startup's nanoparticles, thereby increasing its energy density 5x over alkaline cells and boosting power by 320 percent. The first commercial nonrechargeable batteries with this increased capacity will be announced by an as-yet-unnamed major U.S. battery maker in the second half of 2008...

Energy density 5x tapi boosting power 320 persen? Jadi untuk volume yang sama, batere akan 5x lebih panjang umurnya atau 3.2x?

Akar teknologi yang dipakai sama: nanotechnology, tapi belum sampai 10x dari kapasitas batere sekarang sih, lagipula nonrechargeable. Tapi paling tidak few years bukan 10 tahun lah :D

Pengen Batere Notebook Yang Tahan 40 Jam

Dari Slashdot, diambil dari www.news.com:

Cui has filed a patent on the technology and is considering formation of a company or an agreement with a battery manufacturer. He expects the battery to be commercialized and available within "several years," pending testing.

several years = 10 tahun? *sigh*
