Help Key 14443-B Necta Astra

Hi To all,

New owner of a pm3, i'd like to play with my coffee tag.

Here is a picture

FluxBB bbcode test

With a pn533 on linux i can nfc-list that:

ISO14443B-2 ST SRx passive target(s) found
ISO/IEC 14443-2B ST SRx (106 kbps) target:
    UID : ce 33 c2 44 8b xx xx xx

What about this tag, any idea ?  I can use it in any different machine (same mark) credit will be the same, machine are not on lan or gsm wan.

Which command, script i can use to begin and extract key & bin/hex.

Thanks !

Re: Help Key 14443-B Necta Astra

...it say 14443B...  maybe a good starting point is to use those commands?

and use the latest source on github,  Piwi just added better signal support for 14B..

Re: Help Key 14443-B Necta Astra

You should use the offical pm3, latest source,    compile an flash fullimage, 

look at  "hf 14b"  commands.   Read a datasheet for 14443-B and understand the commands and  try using the "hf 14b raw" to send it.

Re: Help Key 14443-B Necta Astra

Thanks for your answer.
Can i use precompiled image or better to do it myself ? In general
I use my debian server for that, but for first testing if i can fast check with a clean precompiled version..

For the datasheet, i agree, i don’t have problem with mifare for exemp’e, only this tag, i know it’s dumpable some guys do it with mod after..

Re: Help Key 14443-B Necta Astra

You have a SRIX4K tag,  try

hf 14b srix4kread

Re: Help Key 14443-B Necta Astra

pm3 offical,  a bit different from mine smile

srix4kread  is the one for you.  Before you didn't get the tag recognised either,  but now you do. So use this one.

Re: Help Key 14443-B Necta Astra

There is no dump / restore command for 14b currently in the pm3 client.
feel free to add it smile

Re: Help Key 14443-B Necta Astra

I will have a look on source to try to make something in this way :-)

Other, after charging key, i log before one amount and after an other amount. (1.28 to 3.28 e)

I don't see where the part of the amount, because several block change after charging, do you think it's something like date, hour, number of coins ?

Because for the moment i can't dump and write on the fly, i send contents at adress manually but what about CRC ?

I use  for exemple hf 14b sriwrite 1 12 7401cf04   seems to works in write.

Question, is there a tool to calcul hex write format, because if i send  "sriwrite 1 12 7401cf04" it write 04cf0174, must so reverse opération "sriwrite 1 12 04cf0174' to write good value.

Other, i don't know why, impossible to write in block 5, was working at test begin and not now anymore.

I send "hf 14b sriwrite 1 12 0a00d7fb"  and got content 00000... #db# Address=05, Contents=00000000, CRC=defc

Any idea ?

Thanks for your support !

Re: Help Key 14443-B Necta Astra

I test today my 14443b after replacing some data with no success, my old credit has been deleted.
I try new data, but like i can’t write correctly on block 05 i suppose it will crash again.

Got question, i test write and raw command, does i need key manager or something like that?

Can you move my post in 14443b section ?

Thanks

Moved.

If you could identify the system/brand/company, then that would be great.

Re: Help Key 14443-B Necta Astra

I made new test today with 2 keys, now no works anymore
On machine, no charge possible with my keys, detected like bad keys.
I’m going to try restoring old block. Except 05, unmodifiable for now.

Re: Help Key 14443-B Necta Astra

If you look at the blocks that changes from before and after one use.
you should be able to"reset" back if you can write to the tag.

Re: Help Key 14443-B Necta Astra

Yes, that’s what i do, after charging, and uncharging.
But strangely no works. I suppose it comes from block 05 that i can’t write correctly.
Maybe protected ? Easy Tool can help me ? Or same as manual command.

A full copy of the tag will be more usefull to play, because
Sending reversed hex manually is long !

Re: Help Key 14443-B Necta Astra

I think my 2 previous Tag are bricked, not detected anymore on coffee machine. I suppose the problem comes from block 05 change.

New test today, with 2 other Tags

First one with 0.02 euros on it  and second with 0.14 euros on it.
I can't see where euros are stocked, any idea ?  02 & 0E ?

hf 14b srix4kread is good for reading tag ? or must use raw ?
