The most brief introduction of the next M1 card data structure


at present, there are 2 kinds of M1 cards, respectively, S50 S70, in fact, the capacity is not the same, S50 for 1Kbyte S70 4Kbyte
The main introduction S50 that 1K card 4K card rarely seen


S50 Capacity 1kbyte,16 sector (Sector), each sector 4 blocks (block) (blocks 0~3), a total of 64 blocks, by block number address as 0~63.
each sector has a separate set of passwords and access controls.
the No. 0 sector block 0 (that is, absolute address 0 block) is used to store the manufacturer code, has been cured, cannot be changed.
other sectors of the block 0, Block 1, Block 2 is a data block for storing data, Block 3 is a control block, storing password A, access control, password B.

above probably said the next structure, in fact, we only need to care about the red box of the data on the line, others want to know their own Baidu it!
<ignore_js_op>

======================== I am the happy dividing line =========================


Let's say a few simple examples to save the old people from asking.


Some cards use the plaintext, as shown in
Yes, this card is due July 7, 17.
<ignore_js_op>


This card uses 16 of the binary expression, is also a clear
0E 0C 12 expires December 18, 14
<ignore_js_op>


Here are 2 more simple examples.


and some cards. These data with check digit and the whole chunk data represent the date floor and so on, which is calculated by some algorithmCome on.
There is a rolling code, brush a card, the specific chunk of the data on the change once, the data has a regular, and some have no regularity ...
There is a blacklist function, that is, if the data validation can not pass, it will be your carré to the blacklist, your card directly reimbursed, of courseThe property may be restored. So do not change data, light can not be used, heavy card scrap, but also to be caught by the property.
As for the financial card, if you want to eat for free, you can change it!

======================== I am the happy dividing line =========================


someone asked this, maybe.


all blocks of the No. 0 sector of the UID card sold by the baby can be changed. And the card has a backdoor, you can bypass the password, directly read the data, the card's secretcode is decoration, no use!
Fuid is a one-time writable ID number of the card, it is said that the blank can be written once the ID good, can not be changed later. This is against the card reader has anti-system function, there is also called through the firewall ...
CUID ID Number can be used repeatedly erase, no longer worry about the use of a scrap after the problem
There are all kinds of blank cards, in fact, the function is almost.


======================== I am the happy dividing line =========================


send a tool, but set a GUI, ha ... Just for the convenience of use, no technical content ... You don't have to use it.
some time ago someone sent pn532-mfoc-mfcuk-windows This tool, is compiled open Source Library, but in DOS use, operation is not veryconvenient, so took a little time to do a GUI.
using vs C #framework2.0need to install framework2.0 above if unable to run

The program icon is in the Pn532-mfoc-mfcuk-windows folder, very conspicuous!


General use Process
1. Using the default key read if the card is encrypted with the default key, you can read the data directly and then save the data as Key.bump

2. Full encryption card crack key If it is a full encryption card, use this function, may be able to get the key, the success rate is not too high, I hand a bunch ofcard, can have a 5 6 can solve it, some people say this luck and time related, but I did not try to come out, can solve any problem, can't solve,The different time tried many times, still cannot solve to open.

3. Using a known key to read the key or know the key, the key is filled in the known key, and then click to read the data, the dataSave As Key.bump

4. Write the card to write the card before you first read out the copy card data, and then browse the original card data, click the Write Card button on it.

5. Stop forcibly terminate the program to run, because this program is only a GUI, so when the full encryption card crack, need to stop, it is best to useerror or other unknown issues.
