The document used in making lodgments into a current account is

The document used to make lodgments into a current account is the paying-in slip.

Here's why:

A paying-in slip is a small form provided by a bank that allows you to deposit money into your account. When you want to add funds to your current account, you fill out this slip with details such as the amount of money you are depositing, your account number, and your name. You then hand both the slip and the money to the bank teller who processes the transaction for you. Alternatively, it can be used in an automated bank machine that accepts deposits.

Other documents or instruments like a cheque book, pass book, and credit card serve different purposes:

• A cheque book is used to make payments to others; you write cheques to transfer money from your account to someone else or another entity.
• A pass book records transactions for savings accounts, not current accounts, and helps keep track of deposits, withdrawals, and balances.
• A credit card allows you to borrow funds up to a certain limit for purchases, which you then repay at a later date. It does not directly deposit funds into your account.

In summary, when depositing money directly into a current account, the paying-in slip is the correct document used for that purpose.
