..i think the modus operandi of EFDs does not allow these devices to be configured to include missing details of a client/ customer u've just mentioned...the machine helps the business and TRA to track, and keep records of entity's sales and tax information 4easy refference later on when filing tax returns tats y it has no or limited information about the client...if u want a document that has ur details ask them to give u a cash receipt to authenticate the EFD Generated Invoice..
