Yes and no. You have to fulfill the TASO clinic attendance requirement. This can be done at an in-person clinic (held around the state) or through the online clinic instruction videos that are accessible through your TASO dashboard.
You can download the new TASO app from your Google Play or App Store. Just search TASO.
TASO has moved to digital ID cards this year. You will not be getting a physical ID card. But... have you ever actually had to use it? ¯\_(ツ)_/¯
Yes. The rule change is that they are no longer required for use to check the line up prior to the start of the match. Do not let your lineup card interfere with the tempo of the match, but use it if you like.
