【文章內(nèi)容簡介】 ive used to affix the tag on the product. If your tag is going to get frozen or wet, you don’t want it to e off because it no longer sticks. A special coating on the label face may also be needed to resist water.Additional Memory There are tags that have additional memory capacity that may be used to store information such as date of manufacture or expiration, but that don’t affect tag placement so we’ll save that for another discussion.Cost A better performing tag may cost a little more, but it could result in huge savings later on. For example, if you’re debating between the 10162。 tag vs. the 12162。 tag, consider this: a 2162。 difference adds up when you consider thousands, if not millions of products, but look at what you’re paying per year for replacing lost orders. One supplier was losing $3 million per year in lost product before implementing RFID using a 12162。 tag. They tested the 10162。 tag, but it didn39。t perform as well. Using he higher priced tag, they only lost $500,000 per year a savings of $ million per year. That paid for 20,833,333 tags.Where do you stick it?For most products, you can’t just put a tag anywhere on the product and expect it to read 100% of the time. There are several reasons for this:1) The posite materials of both product and the product packaging Radio frequency waves can easily pass through certain types of materials。 while other materials can reflect or absorb the RF. You can’t see this with your eyes, because light waves (and therefore barcodes) reflect differently. The image to the left illustrates how your RFID reader “sees” a box with a flashlight in it. The red color means the RF waves are not passing through the product, while the green areas show strong signal. The tag will read better in the green areas than the red areas.

The metal ponents of the DVD player will reflect the RF waves of the tags used in supply chain operations. If you look closely, you can see there is cardboard packing between the side of the box and the actual player. Since cardboard is a RFfriendly material (something that lets RF waves pass through it easily), it provides a better location for the tag than the area near the metal. 3) How products sit in the case/carton.For supply chain RFID tags, products that contain water can be challenging. Water will absorb some of the RF signal therefore making it difficult for tags to be read. The tag is less affected when there is an air gap between it and the water. Take the case of water (pictured left) as an example. The air gaps between items can be used to improve tag performance. By placing the carton tag at the top on the outside of the box, read performance is good.
