How do I get an open university student card?

Hello there, I'm wondering about the process of obtaining an open university student card. Could you please elaborate on the steps I need to take in order to acquire one? Is there a specific application form that I need to fill out? Do I need to provide any documentation or proof of enrollment? Additionally, how long does the process typically take, and are there any fees associated with obtaining the student card? I'd appreciate any information you can provide on this matter. Thank you!
