On the fourth day, brush the pos receipt when you check into the hotel and issue an invoice when you leave. Can you reimburse me?

I can't. POS machine is the details of UnionPay card transaction and WeChat transaction. This list can only prove the consumer's consumption voucher at a certain consumption place. As the original proof of reimbursement, invoice is indispensable and conforms to the financial system. In addition, some companies with strict financial systems need consumption details. POS purchase signature cannot be a valid reimbursement voucher.
