Use Table 19 to format and interpret the Maximum and Current Connection Speed values,
respectively.
NOTE:
Normally, the application should know the maximum connection speed of the PICCs being used. The
environment also affects the maximum achievable speed. The reader uses the proposed communication
speed to communicate with the PICC. The PICC will become inaccessible if the PICC or environment does not
meet the requirement of the proposed communication speed.
