Japanese to English Bus/Financial Accounting Account statement

I am not quite sure what the 'Katakana-ized' term refers to. It appears in a statement for an account holder with a Japanese postal bank and seems to refer to rent paid by bank transfer from the account holder's deposit account. However, I don't really know if it refers to the type of rent paid or the type of method used to transfer it. This is the problem when terms are spelled out in Katakana and not in kanji, which would at least elucidate the meaning somewhat. Any help appreciated!
