4 Presentation In the world of RFID, many users have encountered the need to check the card technology or even to take a look at the data. The software ReadCard was developed by ISLOG Network in this intent: to provide an intuitive environment to visualize and analyze more than 90% of contactless and contact card used today in the world. Requirements Software components Framework.NET 2.0 Operating system: Windows 2000 SP4, Windows Server 2003 SP1, Windows XP SP2, Windows Vista, Windows 7. Using ReadCard The following pages describe all graphical interfaces and various allowed manipulations on the software ReadCard to read the card data. If you are using the ReadID version, you can directly go to the following page. 4

5 Main navigation bar. Type : Card technology type (Mifare, iclass, DESFire, ) ; ATR («Answer to Reset»): Specific information about the card ; CSN («Card Serial Number»): Serial number supposed unique by constructors. Nothing guarantees this uniqueness (possibility of duplicate due to entrusted constructors). List containing all smartcard readers detected on the system. Complete structure of the card. Total card Memory Free memory (reachable and clean) Detailed header for a specific sector. Current action executed by the software. Basic hexadecimal data read on a specific sector.

6 How to access to smartcard data? The software ReadCard waits a card detection all time on every (or the selected) reader plugged on the system. You can, at any moment, plug a new reader: it will be automatically added to the reader list. The first step consists to put on card on the contactless reader: HID iclass card detected The screen is automatically updated with the detected card detailed. You can also see that three new buttons appear: Refresh the card structure. Analyze the entire card (total memory, available, sectors accessibility ). Reset loaded keys (in the software memory) for this type of cards. Show node properties. Enregistrer les modifications. 6

7 You can now read data on the card. Left-click on a sector or right-click and press Read Data : Note: You can only read sectors which contains data. In our example, it is useless to double-click on HID iclass or Page 0, only Zone Area sectors contain data. If you have access to the sector, data are displayed: You can also write data directly on the card by typing directly the hexadecimal code (in the middle table) or the ASCII characters (in the right table) and then clicking on the button Data that have been changed appear in red color. to store data. 7

8 If you have not access, this message will be displayed (Authentication failed): If you got the access key to read the sector, you can load specific keys by right-click on the sector and Load Keys Please, refer to the Access keys loading part for detailed. One more information is available, it is the name of the reader which one the card has been detected (only if you are listening all reader): 8

9 How to analyze accessible information? To obtain detailed information on the card, an analyzer tool let you see all accessible sectors with default keys (and loaded keys) and the total memory used and free. Put a card on the contactless read and press the button The analysis can take few moments depending on card type: 9

10 Once the analysis is complete, the interface is updated: Three color codes let you know the accessibility to all sectors containing data: Accessible and free sector. Accessible but already used. Locked sector. You need to load specific keys. Memory information is also updated. The free memory results of the sum of accessible sectors which doesn t contain data. 10

11 Access keys loading To give a secure access to the card datas, most of users change the access keys of sensible sectors. You wouldn t be able to read any datas without the keys. To load access keys (read or writes keys) you musst in a first time to select the desired sector(s) (if many sectors are selected, access keys will be loaded on each sector). Right-click on a selected sector and click on Load keys : After the configuration step, click on «Validate. The loaded sectors will appear in red color under the tree view: To unload access keys, you can redo the same action by clicking on Clear keys or use the button which will reset all loaded keys directly. Note: Keys are saved by card type. If you want to read cards which have the same type successively, you will have to load the first time the adapted keys and all next card will automatically have the same keys loaded by default. If you want to reset these keys (come back to the default values), you can press the button or put a different type of card on the reader. 11

12 Formatting a card The complete or partial format of a card must be realised by an authorized user who knows the risks associated of the deletion of many used datas on the card. The first step before formatting concists to load access keys into the different sectors which need to be reseted (if all keys are default keys, you can directly skip to the next step). Once keys are loaded, you have two choices : Partial format: you can format a specific node. Right-click on the node and select Format node : Full format: Only accessible sectors will be reset (with correct access keys). To format all the card, click on the button: During the formatting, access keys are also reset; don t forget to unload the keys before reading the sectors again. 12

13 Properties and header reading Every type of card have different properties. These properties could be affected to the entire card or for exemple to specific pages or sectors for HID iclass and Mifare. Properties can be viewed by clicking on the Properties button: A new window will appear with all the properties: Some cards also have an header for sectors containing datas. These headers can be viewed by clicking on Read Header : 13

14 Send command to the RFID chip This is an advanced mode of handling the contactless card. Please use this option with caution. ISLOG couldn t be implicated in any dysfunction of a card after sending erroneous commands. The send command menu is available by right click on the first node of the card structure: Select the command to send to the RFID chip and click on Send. The hexadecimal code corresponding to the actual frame is displayed on the right. The chip s response is viewable in the Result panel. Depending of the type of the selected command, you will have to fill some additional information. For example, if I select the SelectPage command, I will have to look at the book and page I want to select: 14

15 Save/Backup a card The card s backup let you save raw data directly in a binary file that can be sent to someone for an analysis for example. To save the entire card, right-click on the first node of the card structure. You can also save one particularly item; you have just to right-click on it. Many options are available: Ignore not granted nodes : nodes that are not reachable (need access keys); Include data header : specific sector headers will be saved too; Add node information and Add card information : specific card information will be added to the backup; Exclude blank nodes : do not save empty data of the blank nodes. Select the destination file and click on Save. 15

16 Search/Find data The search always begins from the selected node in the card structure. To perform a search, go to the menu View and Search or directly by using the key combination CTRL+F. Two search types can be used: Hexadecimal : search directly in the binary data hexadecimal data: String : try to find a string in the card that match the entry. Click on the button Find. If a result is returned, the node in which the entry would have been found will be selected and the entry line highlighted: If no one entry matches, the message bellow will be displayed: 16

17 CSN Visualization and ATR description CSN of the card is generally displayed in hexadecimal. The decimal and binary format is accessible in ReadCard. You can also choose the following representation (MSB Big-endian and LSB Littleendian ). This functionnalities is accessible under the main menu View : Or directly under the CSN field: Note: You can also change the diplay by double right click and the representation by left click on the label CSN. An ATR is often used for specific card type. Banking card for example have the same ATR which can be easily recognized. The ATR list is now completed and updated regularly. ReadCard can import such lists to view detailed information on the ATR. The first step consists to load the ATR file: A file named «smartcard_list.txt» is delivered with the software (in the installation path). You can select this file and valid the import. 17

18 If the import process returns successfully, you should get the following message: Once the list loaded, you can refresh the card. If the following button that a description exists for this ATR: is enabled, this means Click on the button: This is an example for banking French card: 18

19 Settings In Options and Settings, you will be able to select the application language: Two languages are available: English and French. Changing the language will not result in a restart, however it is possible that some elements of the windows is not directly translated. Simply restart the application to change it. 19

22 ReadID ReadID is a light version of ReadCard with less memory management functionalities but more chip technologies identification than the regular ReadCard version. In fact, the main difference is the RFID reader provided. Main navigation bar. List containing all smartcard readers detected on the system. Type : Card technology type (Mifare, iclass, DESFire, ) ; CSN («Card Serial Number»): The card identifier 22

23 CSN Visualization and ATR description CSN of the card is generally displayed in hexadecimal. The decimal and binary format is accessible in ReadCard. You can also choose the following representation (MSB Big-endian and LSB Littleendian ). This functionnalities is accessible under the main menu View : Or directly under the CSN field: Note: You can also change the diplay by double right click and the representation by left click on the label CSN. In the case of multi-technological readers like Deister, the CSN word could be known under other definition which refer an unique card identifier. 23
