Methods are presented for facilitating sales transactions by electronic media. A temporary barcode or other design is affixed to the person or personal object during the period of time for which a financial transaction might occur. Before the sales transaction can be consummated, the barcode information is scanned and characteristics about the scanned code are compared to characteristics about other codes stored in a database for the specific time period in question in order to verify the identity of the buyer for a given time period. Once the information is verified, the seller may be authorized to debit the buyer's electronic bank account or charge their charge card account to consummate the transaction or transactions during a period of time. The seller may transmit the buyer's barcode and the buyer transmit the seller's barcode to a clearance center, where the buyer has a smartphone capable of scanning the seller's code.
