Bills of exchange are divided into bank bills and commercial bills. A bank draft is a bill that the remitter deposits the money in the local issuing bank, which issues it and unconditionally pays the holder or payee according to the actual settlement amount at sight. They are suitable for commodity transactions where payment is made before delivery, or where money and goods are settled. Units and individuals can use bank drafts for settlement in various currencies. Bank drafts can be used to transfer money, and shadow bank drafts marked "cash" can also be used to withdraw cash.

Generally speaking, the payment term of a bank draft is within one month from the date of issue. If the payment has not been made after the expiration of the payment period, the holder shall make an explanation within the bill rights period, provide his identity card or unit certificate, and request payment from the issuing bank with the bank draft and settlement notice.

A commercial bill is a bill issued by the drawer, which entrusts the payer to unconditionally pay a certain amount to the payee or holder on a specified date. The payment period of a commercial bill shall be agreed by both parties, but the longest period shall not exceed six months. The payment term of a commercial bill is within ten days from the maturity date of the bill. The holder of a qualified commercial acceptance bill may apply to the bank for discount with the unexpired commercial acceptance bill and discount certificate. According to different acceptors, commercial bills can be divided into commercial acceptance bills and bank acceptance bills.

The full name of a cashier's check is a cashier's check, which is a bill issued by a bank and promises to unconditionally pay a certain amount to the payee or holder at sight. Banknote is divided into fixed-term cashier's check and irregular cashier's check. If the word transfer is crossed out of the face, it is a cash promissory note. The payment period of a cashier's check shall not exceed two months from the date of issuance.

A check is a bill issued by a unit or an individual, and the bank entrusted to handle the check business unconditionally pays a certain amount to the payee or holder at sight. Checks are widely used in settlement in the same city. A check printed in cash is a cash check, and a check printed in transfer is a transfer check. A check without any words can be used for cash payment or transfer. A crossed check with two parallel lines in the upper left corner of an ordinary check can only be used for transfer. Cash cannot be withdrawn. The time limit for presenting a cheque for payment is within ten days from the date of issue. If the time limit for presentment for payment is exceeded, the holder's bank will not accept it and the payer will not pay it.
