Customer Friendly Transactions Bar coded retail transaction card sets with removable matching bar code labels illustrate another multi-functional bar code application. Store personnel have only to snap a sequentially numbered and bar coded card out of a sheet, present it to a customer, and place the matching information label beside the customer card onto a dealer record. Time is saved. Mismatching of identification numbers is minimized. A Growing Number of End Use Application Ideas Multi-functional bar code labels are currently being used in a wide variety of applications to reduce costs, improve productivity, save time, maintain security, and eliminate errors.
Blood banks use piggyback labels to assure record keeping accuracy.
A given piggyback label on a blood bag will carry a quantity of labels with identical bar codes. When blood samples from the bag are sent out for testing, a bar code label is placed on the sample vial to cross reference the sample to the bag. Opportunities for human error are minimized, and accurate record keeping of blood samples and donors is facilitated. Shipping documents with detachable pressure sensitive labels are used to confirm delivery of packages. To reduce book losses, bar coded library labels with encoded security information that can be erased as books are checked out and reactivated after books are checked back in are used.
