Minimum clearances 
Minimum distance from transponder to transponder  
The specified distances refer to a metal-free environment. For a metallic environment, the 
specified minimum distances must be multiplied by a factor of 1.5. 
Table 4- 13  Minimum clearances for transponders

) between reader and transponder, and 
between transponder edge and transponder edge
