When writing on the back of a cheque, the primary requirement is the endorsement, which signifies the transfer of rights or confirmation of receipt. Depending on the purpose, you should include:
- Full Signature: Your signature must match the bank’s records to authorize the transaction.
- Account Details: For a secure deposit, write "For Deposit Only" followed by your bank account number.
- Contact Information: It is often recommended to write your mobile number for communication in case of any processing issues.
- Beneficiary Details: For specific transfers like RTGS, mention the beneficiary’s name and IFSC.
