When a user credential is placed on the reader, initialization, anti-collision is done. The user 
credential is automatically activated and an ATR is built as defined in the PC/SC specification. 
For further information, please refer to section 3.1.3.2.3 of [PCSC3] and to [PCSC3-SUP] 

The ATR of the credential is composed as described in the table below. In order to allow the 
application to identify the storage card properly, it’s Standard and Card name describing bytes 
must be interpreted according to the Part 3 Supplemental Document, maintained by PC/SC. 

Credentials using technology like MIFARE are examples of this: 

0 

0x3B 

Initial header 

 

1 

0x8n 

T0 

n indicates the number of historical bytes in 
following ATR  

2 

0x80 

TD1 

upper nibble 8 indicates no TA2, TB2, TC2 
lower nibble 0 means T=0 

3 

0x01 

TD2 

upper nibble 0 indicates no TA3, TB3, TC3 
lower nibble 1 means T=1 

4...3+n  0x80 

 

A status indicator may be present in an 
optional TLV data object 

0x4F 

Optional TLV 
data object 

Tag: Application identifier  

Length 

1 byte 

RID 

Registered identifier on 5 bytes 

PIX 

Proprietary identifier extension on 3 bytes 

 

0x00 0x000x000x00 

4 RFU bytes 

4+n 

 

TCK 

XOR of all previous bytes
