Explanation:

A letter of credit (LoC) is a document issued by a bank that guarantees payment for goods upon presentation of required documentation. A LoC must state the amount of money that the bank will pay to the beneficiary of the LoC  and what specific documents the beneficiary must present in order to collect the payment.

Usually LoC are used in international trade because they solve problems related to long distances, different laws regarding trade, and not knowing who is the seller or the buyer. Banks charge fees for issuing LoC, but they assume responsibility for making the payment.
