RIFD uses electromagnetic fields to identify and track tags attached to objects automatically. RFID is superior to barcode, because it does not require the tag to be within the line of sight of the scanner.
METI made an agreement with five major convenience stores, i.e. Seven-Eleven Japan, FamilyMart, Lawson, Ministop and New Days, to introduce electronic tags for all products sold in their convenience stores by 2025, which is estimated to be 100 billion products annually. In the past, there was a problem with items that are microwaveable. The metal components in the RFID tag would risk sparking when microwaved. The tags are generally applied to the outer packaging that the consumer would be instructed to remove before cooking (e.g., a cardboard sleeve), but not everyone follows these instructions. So there is still a risk of putting the item into the microwave in error.
However, in January 2019, after 10 years of research, Avery Dennisonlaunched the microwaveable RFID WaveSafe tag, which withstands up to five minutes in a 950 watt microwave.
