While everyone races to find the industry standard, Omron presents their latest offering.
Omron RFID has announced the launch of a new passive EPC (Electronic Product Code) second generation RFID tag which should, according to its specs, deliver high performance whether encoded and read in the United States, Europe or Asia.
For a whole plethora of reasons, regulators in each of these regions mandate the use of different parts of the UHF band:
Japanese UHF tags run between 950 MHz to 956 MHz
European Union tags run between 865.6 MHz to 867.6 MHz range
Some manufacturers address these spectrum variances by tuning the tag to function best in specific parts of the spectrum. For its ‘OneTenna’ tag, for example, Finnish tag maker UPM Raflatac places the RFID chip at one of three different locations on the antenna, depending on which part of the UHF spectrum it will be used in.
Bill Arnold, Omron RFID's chief strategist:
The company's new V750 Series EPC Gen 2 UHF Wave tag functions equally well in all parts of the UHF band, thanks to a design that matches the impedance of the chip to that of the antenna. 
The tag uses an Impinj Gen 2 chip. Arnold says an end user is currently testing the Wave tag on shipments tagged in Asia and delivered to the United States, but did not disclose further details.
According to Omron RFID, the Gen 2 Wave tag will be available in production quantities next month. Pricing information has not yet been released.
