<upd_detl>Reordered kanji.

A quick google shows that this is often printed on the tickets themselves, and that may prompt the frequency of the condensed-kanji form.

IME also gives me the 3-symbol version first.

We didn't even have 引替券, which is more common than 引替え券 (68 examples vs. 164,056 for 引換券). Unless there is a pressing reason, it seems like [sK] is preferrable to two [rk] forms, given just how many かえる kanji can potentially pop up.</upd_detl>

voucher is my intuition, and it's quite prevalent on reverso:
