Medical use for RFID

RFID technology will soon be used to track blood supplies with the hope of reducing the number of patients who are given the wrong blood type.

Technology is becoming more popular with medical firms attempting to prevent breaches in supply chains. Pfizer, whose drugs have been targeted by counterfeiters, has recommended increasing the use of coding technology on packs to improve traceability.

According to research firm IDTechEx, the use of radio frequency identification (RFID) tags in healthcare worldwide will be worth $2.1 billion (£1.1 billion) in 2016, compared with $90 million (£47 million) now.
