2. DUAL-FREQUENCY HF/LF ANTENNA SCALE DRAWING：
Current consumption characteristics
As the card/tag is presented to the antenna face, the current draw of the system will change, depending on the size and type of card/tag and its position, and to some extent on the ambient temperature and supply voltage.
Some indicative values are as follows: these diagrams do not represent the outside of a non-metallic environment and do not include any heater components.
