Starting BioStar 2.4.1, you can use your mobile phone as a smart card with 2nd generation devices and Xpass S2. 
Android phones can work with the 2nd generation device’s NFC features, but iOS phones do not have the NFC feature so it currently can only work with devices which have the Bluetooth feature. 

Mobile Smart Card is supported with the versions below: 

Host card emulation (HCE) was used to implement the mobile smart card feature. 
Most of the latest Android devices use HCE but some devices may not support it. 
Check with your phone manufacturer or the phone specification to see if your phone supports HCE. 
Note that NFC and BLE communication specification may vary by manufacturers and models and there could be difference in performance.
