Kindly ask the employee to submit the request in his own handwriting as a written application, with the reasons mentioned therein, along with his signature, employee code, and name. File this application in the personal file. There is no need for you to provide him with any return letter.
Also, if there is no policy in your company to pay by cash, please refrain from making exceptions. This will only create more work for you. ATMs are as good as receiving salary in cash. Additionally, you will have to create cash vouchers for his salary, obtain his signatures, and file them properly for verification. In contrast, with bank transfers, the process is much easier and the data is stored with an external party (duplicate data). Therefore, it is advisable to refrain from making exceptions.
