Learn Danish: Jeg kan ikke finde mit rejsekort i tasken. - I cannot find my travel card in the bag.

In Danish, possessive pronouns (my, your, his, etc.) must match the gender of the noun they describe. Rejsekort is a compound word ending in kort, which is an et word (et kort). Therefore, you must use the neuter form mit instead of the common gender form min.

Why does ikke come between kan and finde?

In a main clause with a modal verb (like kan) and a main verb (finde), the adverb ikke (not) is placed right after the first verb. The word order rule here is: Subject + Verb 1 + Adverb + Verb 2.

How do you determine the gender of a compound word like rejsekort?

Compound words always take the gender of their final noun. Because the last part is kort, and it is et kort, the entire compound word rejsekort becomes an et word. This rule applies to all Danish compound nouns.

Could I say i min taske instead of i tasken here?

Yes, you could say i min taske (in my bag) and it would be perfectly correct. However, Danish frequently uses the definite form (tasken, meaning the bag) when ownership is already obvious from the context. Since you are looking for your own card, the listener naturally assumes you are checking your own bag.
