Reminders:
1. It is recommended to enable the option “Turn Off Antenna Field if the PICC is inactive”, so
that the “Inactive PICC” will not be exposed to the field all the time to prevent the PICC from
“warming up”.
2. The longer the PICC poll interval, the more efficient the energy saving will be. However, the
response time of PICC Polling will become longer. The Idle Current Consumption in Power
Saving Mode is about 60 mA, while the Idle Current Consumption in Non-Power Saving mode
is about 130mA.
Note: Idle Current Consumption = PICC is not activated.
3. The reader will activate the ISO 14443A-4 mode of the “ISO 14443A-4 compliant PICC”
automatically. Type B PICC will not be affected by this option.
4. The JCOP30 card comes with two modes: ISO 14443A-3 (MIFARE Classic 1K) and ISO
14443A-4 modes. The application has to decide which mode should be selected once the
PICC is activated.
