Chip and Pin is broken

The truth is banks often lie to us to protect their interests. People like Omar Choudary and projects like the SmartCard Detective show us just how much is being hidden from us. If you ever find yourself victim of credit card fraud this might help you to recover your loss. It’s outrageous that even though they know about the loop hole they’re not doing anything to fix it and on top of that if you’re a victim they don’t give you your money back because “EMV is infallible”.

you can read about the EMV interceptor in Omar Choudary’s thesis: The Smart Card Detective – a hand-held EMV interceptor and you can check for more info and source files on his project page.

The Truth Behind SD Cards

The Truth Behind SD Cards

I don’t know that this title make you think off, but i couldn’t express better the subject. We’re talking about SD cards that are not what you’d expect them to be. Sparfun electronics accidentally discovered while looking inside an SD card that it actually contains a micro SD card soldered to the SD pins. The job looks like it is hand soldered so the guys from sparkfun think there must have been a huge batch of microSD cards and a perceived shortage of full size SD cards.

SIM card reader/writer

SIM card reader/writer

Adafruit Industries just announced their next kit: a SIM card reader. Using the kit, you can read or write any SIM card. You could use this for fun things like recovering deleted contacts and SMS messages. The kit looks like a very straight forward design (based on Dejan’s work); the only chip is a hex inverter and the board is powered by a regulated 9V battery.

With all through-hole components, it should be easy to assemble. You can talk to it using the board mounted serial port or connect to the extra pin header using an FTDI USB cable just like the Boarduino. The FTDI option is bus powered, so you won’t need the battery. ladyada has collected some resources in case you want to learn more about smart cards.

Portable Magnetic Card Reader

The HandySwipe provides a portable magnetic card reader interface and display. It collects card data from a “Type 2″ card reader (shown here), and displays the data on a small character LCD screen. Type 2 stripes are by far the most common in use, such as on credit cards and drivers’ licenses.

The device can store up to 50 cards, runs on four AA’s, and has a serial connection to download its memory to your computer in CSV format. It can also download data in a raw bistream format compatable with StripeSnoop, so you can take advantage of StripeSnoop’s powerful parsing and analysis features (LRC error checking, backwards swipes, card type/contents/issuers/etc.)

    This news got my attention because I am a fan of flash memory and I’ve been waiting for some time a big capacity flash memory that can replace the Hard Drive from a computer. I don’t know if this memory could replace a Hard Drive but is definitely a big step forward. Samsung announced an advanced process to pack the maximum of 16 of the multi level cells just 30 nanometers. That means they are able to deliver 64 gigabits of flash memory onto one chip.

Samsung Prepares the 128 GB Flash Memory Card

    The process was called self-aligned double patterning technology (SaDPT). By using the process described above, Samsung can produce 128 GB NAND memory card. Consequently, the price for memory cards will drop, which is a good thing for the consumers. Also, the high storage cards could replace the traditional hard disks being more efficient. But we have to wait till the technology will be released, maybe in 2009.
