About operating magnetic field
Contactless Smart Card Standard ISO 14443 and Felica, RFID tag Standard ISO 15693 is defined
magnetic field strength (radio wave strength) for communicating with card and tag, and this is
standard of communication distance with card and tag.
But magnetic field strength described in this section is imaged 85 x 54mm (4 times scroll antenna)
card tag, therefore communication distance will be changed by style of tag and number of scroll
antenna. (ex. If tag style will be small, antenna sensitivity will be bad, therefore communication
distance is not same.)
This description can not be guaranteed all cards and tags communication, therefore please execute
enough operation test before installation.
Scanning distance (Reference)
Scanning distance of RDIF tag / Contactless Smart Card will be different with antenna style or
number of scroll or IC chip type.
The following reference is information of scanning distance at each style of RFID tag / Contactless
Smart Card. This is just reference value, therefore please execute enough operation test before
installation.
