RFID: AT90RF135602- Smallest RFID Reader

The AT90RF135602 definitely needs a nickname. Even in 8-point type it's too big a title for the world's smallest RFID reader!

AT90RF135602 (see what I mean?) is the latest RFID collaboration of California-based Atmel and UK-based Innovision Research & Technology. This single chip RFID reader is a mere 12mm by 12mm by 2mm. (For those of you who like to travel ultra-light, check out the scaled down 6mm by 8mm by 1.5mm version).

The AT90RF135602 reads and writes to 13.56 MHz RFID tags and smart labels, is optimised for a 2.8V battery operation, and is compliant to ISO/IEC 14443-A parts 2 & 3, making it especially suited for small, battery-powered handheld devices.

I can see how this smaller-than-dime-sized RFID reader may be helpful for NAVI (Navigation Assistance for the Visually Impaired) and other handheld applications. Smaller readers make handheld devices less obtrusive and more comfortable to carry. Good news for those using NAVI or taking self-guided museum or walking tours.

I can see how the AT90RF135602, priced at a relatively low $3 per unit (in quantities of 10,000) may be attractive to RFID managers trying to achieve maximum efficiency at minimum expense. It's inexpensive to operate, field programmable and upgradeable, so it's an investment that will grow with your operation.

I also see that as RFID readers become smaller they become more difficult to see. Easier to forget.

RFID tags continue to shrink, and in some cases have disappeared altogether, replaced by smart labels and smart inks. Too many consumers aren't even aware of RFID tags yet, and it's becoming more and more difficult to see them.

Technology naturally trends toward more power in a smaller footprint. That's one of the ways we measure progress.

As we trend toward ever-more progress, let us also trend toward ever-more citizen awareness. Let's make sure that we can look back on the AT90RF135602 as a really cool RFID reader that advanced our culture and improved the quality of our lives. And had a great nickname.
