Do all countries use the same low,high,and ultra-high frequencies?

Most countries use 125 kHz or 134 kHz for low-frequency and 13.56 MHz for high-frequency RFID applications. Europe uses 868 MHz and US uses 915 MHz for Ultra-high frequency RFID applications. Some countries like Japan do not allow any use of the ultra-high frequency spectrum for RFID applications. To tackle this problem, some tag and reader manufacturers are providing devices that can work at more than one frequency.
