dallaskorben, would you like a smart card to test it out? The laundry facility I go to dispenses cards for free. Minimum balance price is $5.00. I say it was free because initially if you put a balance in it the card comes with the balance you entered, i.e. 5 dollar bill. Some other places charge up to $2 for the new card. If you'd like we can arrange something so that the card can be mailed to your location. Here is what I know so far (posts from here and other locations). A software called CVA can add amounts and a stand alone unit can add/check amounts. Each location, that is a place or business that purchased this ESD system has a unique client number. This client number is embedded along with the card amount. Smart card readers are programmed to work with this unique client number at this location/business only. Each ESD moneycard has unique serial number which I recently read that it is crucial in making this moneycard to work with the reader. I will attach what I found later. So basically, the cleanest hack (or crack) is to dump it as a file, use hex edit to change the value and rewrite it to the card. But it's not as easy as it sounds. Rats!

blowfish, Good work. I should have attached pictures as well. I also have a link at the end of the post that might interest you. I don't have any attack angle but I'll give what I've found and perhaps someone can make sense of it all. First, pictures of my laundry machine coin (smart card) slot and control panel covers taken apart. Correction: Originally I stated that there were 4 wires. I was incorrect. There are 6 wires--(top 3) 2 white, 1 brown, (bottom 3) 1 red, 1 yellow, 1 gray Then, these 6 wires connect to various locations on the control panel, where a set goes to status light and the rest goes to drying selections (pictures are for dryer only) blowfish, I found this link while in search of breaking satellite cards. I'm not sure if this is useful but if you do find it useful please share it with us :) Let us know which reader/writer you're using and if you were able to read them at all. The site states that it was developed for Windows environment. I can't make any sense of which reader/writer is compatible or, is it just any windows compatible reader/writer will do? http://www.literatecode.com/2007/06/03/smacadu/ Good luck.

I have been following this topic for some time and I decided to participate after a break-through. And I really appreciate StarchyPizza's solution: keep it simple--work smarter not harder. However, my break-though (not so literally) was actually disassembling the protective cover from smartcard reader protective cover to washer/dryer control panel. So now that I have exposed washer/dryer's wiring I am all excited what makes it tick. And I am in an experimental mood (so don't lecture me about breaking the law--I'm coinless :)) My questions are: there are 4 wires coming from smartcard reader and connects to another 4 wires with a opaque, square connection type which is made with plastic material and a snap on, I believe. Would I be able to bypass (if this is the right term) by connecting them manually, that is to hot-wire them, together to start the cycle? If so would a Macguyveristic paper clip will do the trick? How many wires do I need to connect them? Is there a better way? Should I arrange my funeral before I attempt, fearing an electrocution? Do you need photos to determine the precise operation dealing with delicate instruments? I am willing to upload some photos!
