What is one recognized method for international cheque clearing?

International cash letters are a recognized method for international cheque clearing because they facilitate the collection and processing of cheques drawn on banks located outside of the payer's country. This method involves sending batches of cheques to a central clearing location, where they are processed and settled with the corresponding banks.

International cash letters streamline the cheque clearing process by grouping multiple cheques together, which reduces handling costs and accelerates the exchange of funds. This system is particularly important in the context of international transactions, where different currencies and banking regulations may complicate direct cheque processing.

In contrast, the other options—wire transfer, ACH payments, and mobile payments—represent different methods of transferring funds, rather than specifically addressing cheque clearing processes. Wire transfers and ACH payments are electronic methods that do not involve cheque processing, while mobile payments focus on instant payment solutions typically used for point-of-sale transactions rather than for clearing traditional cheques.
