Table 2-4. Current consumption
1
Dedicated NTag216 tag may increase current consumption up to 90mA and value depends on distance and
location between tag and antenna (higher consumption is when tag is closer to the antenna).
2
Any metal object located in electromagnetic flux will increase current consumption.
