The whole new-branded UHF Water Tag modeled HKRST-W01 has come to the market! In the past, RFID tag was constrained by water content such as sweats from human body or melted water from frozen products. However, it is no longer a problem for water tag as it is readable when emerges in water. It provides up to 20cm reading range by using handheld reader even when it is soaked in water. It can also be made in any other waterproof encapsulation. Be kindly reminded that for diving or underwater situation, make sure your UHF reader is waterproof like the tag.
