The TT Token or App need to be close to the SEGW (1-25cm) to be detected.
All variants of the TT Token, and the TT App on most mobile phones, are compatible for use with the SEGW. (Some mobile devices implement a limited set of Bluetooth features and will therefore not be compatible with the SEGW). Please note that physical barriers (such as thick phone or token casings, hands) may weaken or block Bluetooth signals from getting through, especially where they fully conceal the device’s Bluetooth antenna.
TT App users will need to use a compatible mobile device^ updated to version 2.4 and above and ensure that the TT App is active by displaying the TT App on the phone screen.
^ Some mobile phone models (estimated at 6-8% of all the phones, mostly Androids) are not compatible with the SEGW. The SEGW is unable to detect them due to their different Bluetooth configurations.
