A bar code reader system includes a record, a bar code reader, a decoder, a processor, a transferring element, and a printer. The record includes a substrate with an information area containing first data removably encoded on the substrate in an error-correctable machine readable format and text. The bar code reader converts the first encoded data from the record into electrical signals which are decoded by the decoder. The processor encodes second data entered through a keyboard, and generates transfer drive signals for controlling the transfer of the second encoded data onto the record. The transferring element detects the presence of the first encoded data on the record, and in response to the drive signals when the first encoded data is present on the record, subjects the record to an erasing operation to remove the first encoded data. The printer then prints the second encoded data on the record.
