What is a blue screen transaction in banking?

Blue screen is a method of closing trade deals such as commodities. In this business, lots of people try to use your banking information and purchase the item you want or obtain a line of credit. Blue screen allows the buyer and the seller to view the other's information. The seller shows his proof of the item (which is usually worth a lot of money and secured in a bank) while the buyer shows his proof of money. It is just a more secure way to gather this information with blue screen. A log in and pin number is needed to complete this transaction.
