Here it is my sheet to automatically decode any Hex 10 digit number (mainly used for EM4100); feel free to use and modify at your pleasure and also add functions and other decoding patterns when you discoverw them ! It also ancode the T55x7 block0 (configuration)  wink

Credits given in the sheet !

I have a problem decoding to dec the IK3 DEZ15, in excel i receive this value -5,48681E+11    for 0102b0c1fd ID (revesed = 80400D83BF), i think the problem is that the number decoded to dec is too long... any help with excel sheet ?

#4 Re: Questions and Requests » RFID UID Calculator? » 2014-08-18 21:19:22

There is a little error:
DEZ 3.5C          = digits 5,6 hex (and not 4,5) converted to dec "." last 4 hex converted to dec

Great work marshmellow wink I was near, you were faster  tongue

#6 Re: Questions and Requests » RFID UID Calculator? » 2014-08-14 16:28:45

Mmmm there must be an error... IK3-Nummer DEZ 15 it's the same as the other one you posted earlier... are you sure other values are correct ?

#7 Re: Questions and Requests » RFID UID Calculator? » 2014-08-13 21:14:14

I found some correlations but more examples are needed; my preliminary (very simple) analysis suggests that it will be probably impossible to obtain back the full 10 HEX ID starting from the already converted value, only a part should be "recoverable". If you can provide more examples I can try to investigate deeper and dismatle this supposition.

He clearly wants to fraud so i think he should study mifare pdfs before asking any other questions.

#9 Re: Windows Client » Compiled Windows Client - Download » 2014-07-17 20:45:48

I remember i had to manually add some (7-8) oenssl files that were missinig; then i installed openssl to cygwin and all compiled fine so i cannot reproduce the errors right now.

I man, it seems that your antenna is not as good as it should be... can you test with a better antenna (higher voltage) ?

#11 Re: Windows Client » Compiled Windows Client - Download » 2014-07-16 15:42:38

You are welcome. Your compiling problems are probably dued to the new DES encryption/decryption algos and maybe iClass stuff (I don't remember exactly); you can find them using google looking at the error it gives you while compiling (usually missing files). Most of them should be inside the openssl repository source code.

#12 Re: Windows Client » Compiled Windows Client - Download » 2014-07-16 15:29:40

Please do not flame this thread; people "thinks different" and we should try to find a common ground using dialogs to go further; if the common ground is "not available" well... just ignore the person that cause you troubles, he probably lives FAR away from you wink

#13 Re: Windows Client » Compiled Windows Client - Download » 2014-07-16 12:17:07

Thank you for your post siop, unfortunately I don't agree with you; he asked for a thing that I was able to give and I decided to give it, that's all (no proud, no glory); he will be responsible for what he is going to do with that (remember that iClass code is still "preliminar").

Remember that any new version will need to be recompiled so he will be always "hanged" if he doesn't find the way to compile it himself.

I think that helping the community is the best thing (with the exception of explaining how to steal/fraud credits or stuff like that on tags), you will never know what is going to happen when you help someone wink

#14 Re: Windows Client » Compiled Windows Client - Download » 2014-07-15 21:00:19

@RadioWar: Here it is (windows only with firmware and bootrom). No support for this, compiled only, no windows GUI nor android addition/implementation/support.

New "official" compiled version (win+gui+android) will be out when all new stuff (iClass included) will be merged in the main trunk.

#15 Re: Windows Client » Compiled Windows Client - Download » 2014-07-10 17:58:31

Thanks for pointing that out, I will look into the reason why it was missing and I will add it in future releases.

#17 Re: Windows Client » Compiled Android Client - Download » 2014-07-04 09:05:41

Yes it is all VERY stable under android; anyway is still quite "experimental" because new pm3 functions (including DES/3DES) are new so I think this is the reason why the patch is not "committed" to github or something like that. Anyway all that was not possible without jonor contribute (and you code of course) ! So thank you for answering-back wink

Here it is (the re-uploaded patch file).

Just reading the id with the correspondant command and converted it to bin.

#20 Re: MIFARE DESFire » Libfreefare » 2014-05-19 19:52:32

02 and 03 are "configuration bytes" used in rfid smartcard ISO14443A. For what I understood 02 is used if a simple answer is waited from the card while 03 if some more series of commands are needed (this is only an opinion, datasheets are a bit vague about them). It is different from real contact smart cards; thsoe one don't need that byte.

#21 Re: MIFARE DESFire » cryptlib inside the arm? » 2014-05-19 19:27:30

Try to increment the "waiting for tag answer" time; I had the same problem with epassports and increasing that delay makes the answer to appear (if I am correctthe default value is .

#22 Re: Windows Client » Compiled Android Client - Download » 2014-05-15 11:08:54

To be able to use android pm3 client with the latest sources you need a new patch that officially I do not support (for now) because of major changes that are actually under development (openssl crypto stuff in particular). You can find my Android latest patch here (copy/overwrite actual source code with the files in this archive).

Again, i do not offer support for this.

I (manually) extracted uid of an em 57xx diameter 2.5cm tag with that cd case antenna, how small tags do you want to read?

A smaller tag than 2.5 cm as i stated before (PCF family):

Coil is probably smaller than 1 cm.

I totally agree with you except for this:

It's not my fault if the seller ships with not appropriate packaging or if his boards are more fragile than normal. He can avoid that problem shipping insured or improving the packaging. I cannot pay for other's faults!

In my opinion seller must tell BEFORE shipping and buyer must ask BEFORE SHIPPING what conditions are within the shipping itself (type of shipping, type of packaging, insurance,  fargility, returns, etc.) because shipping is a quite critical part in a transaction where those kind items are involved; if you think that the seller's shipping/returning policies are not enough (secure, cheap, etc) for you, you must not buy from him; probably you have been "deceived" by other users'good experience.

For referral have a look at Gaucho's group buy experience; he was simply PERFECT in all process steps. This is how things should work.

I can only thank you for sharing your experience with us and I hope the seller will change your mind and help you some way.
