Metro & Bus Prepaid Card in Guangzhou can be use in Shenzhen and Xiamen?

I am wondering if i purchase the value added prepaid card for metro and bus in the city, then when I go to Shenzhen, will I able to use it? I understand that Xiamen has no metro but there is BRT, will the same card works in Xiamen or I need to purchase in Xiamen again? By the way, for which type of bus I can use that prepaid card? Does it work on HSR?

Thank you!
