Are all PIO cards invalid now?

[tagetg]

Hello Folks,

I read on the CKGS website that handwritten PIO cards will be invalid after Sep 30th 2020. Are the machine-readable still valid or they are invalid too. I realize that we cannot travel with a PIO to India now because of COVID restrictions. But are the machine-readable PIOs valid for future travel?

Also, how can I verify if the PIO card is handwritten or machine-readable?
