AS5678 is a requirements specification created by SAE International for the production and test of passive only RFID tags for the Aerospace industry. An AS5678 RFID tag is for use in the aerospace industry. The use of radio-frequency identification (RFID) in the airline industry will get a start with the expected availability of aerospace-standard RFID tags by the end of the year. “That’s what we believe. If it comes to fruition, we’ll be pleased,” said Daryl Remily, deputy program manager of the Boeing.

With RFID UHF tags, there is a general rule of the thumb: The larger the tag, the longer the read range. This is generally true when comparing tags from the same time period. As with any technology, performance improves while the size decreases over time. Therefore, a 4′ x 4″ tag from 2005 will generally not perform as well as a 2″ x 2″ tag from 2008.
A critical component is the antenna design. Unfortunately, there is no one best antenna design. The optimal design is dependent on the application which includes form factor, size limitations, dielectric characteristics of the material to which it is being attached, frequency optimization, etc.
Another general rule of thumb is that a single dipole tag properly lined up with a linear antenna will have a longer read range than a dual dipole tag with a circular antenna. In my earlier post about RFID antennas, I discussed the difference betwen linear and circular antennas.
Although this is a high-level view, the basic RFID tag factors which affect read range are:

The next in this series will discuss how the item itself affects the read range.

As the mom of two little girls, I am becoming increasingly aware of environmental issues and steps that I can take to make a difference for them and future generations. I use energy-efficient lightbulbs, reuse plastic containers and bags as much as I can, turn off the lights when I don’t need them on and we always make a point to recycle. So when I saw this article about Kraft and its recycling program I was thrilled. Here’s a big manufacturer taking steps to help our environment.
Check it out. Kraft foods has started a pilot program where they reward people for recycling! According to RFID Journal, “Kraft is the “official food sponsor” of RecycleBank, which has been expanding its offering across the United States with technology to weigh recycling bins as they are lifted into the recycling truck, while also recording whose recyclables are being weighed. The consumer can then use that record to download a variety of coupons and other rewards, based on the amount of recycling they did.” Read the article.
So how does RFID play a role? Each bin has a RFID tag and each customer has a unique ID code on their bin and to use when they log in online.
How awesome is that?!? Let’s hope some other manufacturers join in the program too.
