Suprema Mobile Access uses BLE and NFC to communicate between devices and card. If you want to use Bluetooth communication in the site, you need to set the installation distance between each Suprema device to at least 1 meter. And if there is a wall between the device, it is much more advantageous for reducing communication interference.


 This is due to the specification of Bluetooth technology, and if the distance between devices is less than 1 meter, a problem may occur in your Mobile Access card authentication.


 Please do not confuse the document related to the installation of the device provided by Suprema before is for using the RF card.
