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.)
