Structure

BS2CSNCard

typedef struct {
   uint8_t type;
   uint8_t size;
   uint8_t data[BS2_CARD_DATA_SIZE];
} BS2CSNCard;

1. type

   The code value of card type. The card type is to indicate the purpose of the card. When transferring a user from device to server, the Access card will be used only to keep the issue history, since the Access card will work on its own without any user information.

   Value	Description	Used Format
   0x00	Unknown card
   0x01	CSN card
   0x02	Secure card
   0x03	Access card
   0x06	QR Code
   0x0A	Wiegand card	BS2WiegandConfig.format (This format is used when BS2WiegandConfig.CSNIndex and BS2WiegandConfig.CardMask is set as 0)
   0x0B	Config card
   0x0D	Custom smart card
   0x1A	Wiegand card	BS2WiegandMultiConfig.formats[0]

   0xFA	Wiegand card	BS2WiegandMultiConfig.formats[14]

2. size

   This is the size of the data buffer. This field needs to be filled with a fixed value as '32'.

3. data

   The data of card template.

   In case of Secure Credential Card (SCC), users need to have card information which includes Card ID (24byte), issueCount (4byte) and TimeStamp (4byte). Also, cardObjs array of BS2UserBlob structure should be filled for SCC cards and the user should be updated after SCC issuing.

   情報

   You can use any value as long as the data and the cardObj in BS2UserBlob match.

   TimeStamp or issueCount is an operational flag for better management but there's no validation check for TimeStamp or issueCount on the device.

BS2SmartCardHeader

typedef struct {
   uint16_t hdrCRC;
   uint16_t cardCRC;
   BS2_CARD_TYPE cardType;
   uint8_t numOfTemplate;
   uint16_t templateSize;
   uint16_t issueCount;
   uint8_t duressMask;
   uint8_t cardAuthMode;
   uint8_t useAlphanumericID;
   uint8_t cardAuthModeEx;
   uint8_t numOfFaceTemplate;
   uint8_t reserved[1];
} BS2SmartCardHeader;

1. hdrCRC

   Value of card header checksum. (cardCRC - reserved)

2. cardCRC

   Value of card data checksum. (BS2SmartCardHeader.cardType - BS2SmartCardData.accessOnData)

3. cardType

   Code of card types.

   Value	Description
   0x00	Unknown card
   0x01	CSN card
   0x02	Secure card
   0x03	Access card
   0x0A	Wiegand card
   0x0B	Config ​card ​

4. numOfTemplate

   Number of fingerprint templates.

   Based on AoC structure, template data is stored in BS2SmartCardCredentials.

   Here you can store either fingerprint or face template. Both fingerprint and face templates can not be stored together.

   Thus, you have to set numOfFacetemplate = 0 if you want to store fingerprint template data.

5. templateSize

   Size of the template. A normal fingerprint template is a fixed 384 byte.

   If you are using a smart card the default in BioStar 2 is 300 bytes and you can change as required but we recommend that you set it above 300 bytes because if the template size is too small it can cause fingerprint matching issues because of the lack of information in the template.

6. issueCount

   Number of smart card issue count.

7. duressMask

   Mask for whether there is a duress finger.

8. cardAuthMode

   IR Face based Card authentication mode.

   Visual Face based Please use cardAuthModeEx instead

   Value	Description
   2	Card only
   3	Card + Fingerprint
   4	Card + PIN
   5	Card + Fingerprint or PIN
   6	Card + Fingerprint + PIN
   254	Cannot use
   255	Not defined (System defined mode)

9. useAlphanumericID

   Flag of usage of Alphanumeric ID

10. cardAuthModeEx

    IR Face based Please use cardAuthMode instead

    + v2.7.1 Visual Face based Card authentication mode

    Value	Level 1	Level 2	Level 3
    21	Card
    22	Card	Face
    23	Card	Fingerprint
    24	Card	PIN
    25	Card	Face or Fingerprint
    26	Card	Face or PIN
    27	Card	Fingerprint or PIN
    28	Card	Face or Fingerprint or PIN
    29	Card	Face	Fingerprint
    30	Card	Face	PIN
    31	Card	Fingerprint	Face
    32	Card	Fingerprint	PIN
    33	Card	Face or Fingerprint	PIN
    34	Card	Face	Fingerprint or PIN
    35	Card	Fingerprint	Face or PIN
    254	Cannot use
    255	Not defined (System defined mode)

11. numOfFaceTemplate

    Number of face templates.

    Basic size of template is different between fingerprint and face (Fingerprint: 384, Face: 552).

    You can consider the total size of templateData in BS2SmartCardCredentials.

    Based on AoC structure, template data is stored in BS2SmartCardCredentials.

    Here you can store either fingerprint or face template. Both fingerprint and face templates can not be stored together.

    Thus, you have to set numOftemplate = 0 if you want to store face template data.

12. reserved

    Reserved

BS2SmartCardCredentials

typedef struct {
   uint8_t pin[BS2_PIN_HASH_SIZE];

} BS2SmartCardCredentials;

1. pin

   Value of PIN.

2. templateData

   List of fingerprint template data area, which can be stored up to 4 fingerprint templates.

BS2AccessOnCardData

typedef struct {
   uint16_t accessGroupID[BS2_SMART_CARD_MAX_ACCESS_GROUP_COUNT];
   BS2_DATETIME startTime;
   BS2_DATETIME endTime;
} BS2AccessOnCardData;

1. accessGroupID

   List of access group IDs.

2. startTime

} BS2SmartCardData;

1. header

   Smart card header.

2. cardID

   Card ID that will be used on the card.

   Access on Cards will need to use the 32 byte array for the card ID.

   Secure Credential Cards will need to use a 24 byte array for the card ID.

   In case of Secure Credential Card (SCC), users need to have card information which includes Card ID (24byte), issueCount (4byte) and TimeStamp (4byte).

   Also, cardObjs array of BS2UserBlob structure should be filled for SCC cards and the user should be updated after SCC issuing.

4. accessOnData

   Data area the AOC card uses, which carries the access group information.

}BS2Card;

1. isSmartCard

   Decides whether it is a smart card.
