You can ensure an added level of security by opting to use deposit-only stamps. These have a fourth line in the stamp that reads ‘FOR DEPOSIT ONLY.’ You can opt to put the next line as the name of your company. The last line can be the details pertaining to the bank account, i.e. the bank account number, branch, etc. You can make sure to put the details of the account in which the check needs to be deposited thereby ruling out any aspect of misplacement or misuse of funds.
