Tier1 Post-study work visa fee

Hi Guys,

Today i applied for the Tier 1 post-study work, i paid the fees using the UK postal order with an amount of £400 payable at 'Home office' but i forget to mention my name & date of birth on the backside of the postal order. I attached the postal order to my application and sent it by using the Royal mail special delivery.
Please anyone suggest me, if this effects the processing of my application or not.

Thanks,
gary
