Receipts should be requested for all transactions.
You are advised to request for receipts after you have completed your transactions. The receipt should contain the details of the particular money changer and the transaction. You may find the directive from MSB Act 2011 & Guideline on Governance and Operational Requirement on Conduct of MSB. Please note that mere calculator printouts should NOT be accepted and you should insist for official receipts. Official receipts will be useful in case of any disputes between the money changer and the customer.
