The Gen2 standard is adopted by Wal-Mart, Target, and the DoD and is the de-facto definition of passive RFID. Over 200 Million Gen2 passive RFID tags are consumed each year (as of 2009). This makes the Gen2 the most popular RFID tag and it has destroyed the future usefulness of HF RFID and LF RFID solutions.
Why Gen2 is simply amazing - Read ranges from 1 inch to 100 feet - Other RFID technologies can not compete with the wide range available
- Low cost - Chips average 20 cents but in massive quantities are in the low 10 cent range. Other chips cost $1+, even in large quantities.
- Density of chips - Over 300 Gen2 RFID tags can be read per second. Other technologies one or two per second.
- Early adoption - Other technologies have been around longer and are showing no major sign of progress. Gen2 has a massive inflow of new hardware and technology that is leapfrogging it past competitors. Areas where other chips excel (secure communication / crypto) are proving to be weak due to easily crack able schemes.
