Which ST25R reader can achieve a 10cm read distance in ISO15693 with a Molex antenna?

I have a specific application where I need to detect the presence (or absence) of a ISO15683 tag at a range of about 10 cm using a Molex 146236-2102 NFC Antenna. Is there an appropriate STMicro product?

    Hi,

    looking at the mentioned Molex antenna it is 15x25mm only. The range numbers Molex is providing mention for this antenna something like 50-60mm max.

    I am skeptical that the envisioned range is possible on any NFC reader.

    Of course it does not only depend on the Reader but also on the tag.

    BR, Ulysses
