pcb traces instead of connector

Thanks , but I am not sure what is this answer, you just showed me usb connectors that where invented 20 years a go, whats new ?

I was looking for a new way to connect 2 pcb's that is not ugly (like shields) and its tiny like usb micro (which is old)

Some solution like LittleBits (magnets) which is sexy and not "technical" , but something not expensive.
