Instead of the ordinary bar coded stick-on labels, we can use RFID inlay stick-on labels. These have a printed portion, as well an RFID tag inlay, which can be either a read only or a WORM (write once read many) type. This tag can be read by RFID readers mounted at various locations on the conveyor belts.

The RFID solution is to embed a tag into the blood bag label itself. The paramedic who transfuses the blood can scan the bag before transferring. He/she typically enters the patient ID number, or in a better system, the patient also has a wrist band RFID tag which identifies him uniquely.

A typical RFID solution would be to use industrial, metal friendly and RF noise friendly tags. This is because standard RFID tags may not function correctly in an RF noisy environment due to the large amount of welding machines, cutting machines and so on which generate a lot of Radio Frequency noise.
