Riepilogo

• Ceramic Material: The R4 ring is made of microcrystalline zirconium ceramics, with excellent refractive index and dispersion performance, giving off a unique round luster overall.
• Nano Characteristics: The nano characteristics of external rigidity and internal flexibility are attributed to the low thermal conductivity of microcrystalline zirconium, which gives R4 a warm and jade like touch.
• Upgrade Circuit Structure: The newly designed circuit structure significantly reduces the electric field interference between various modules, and increases the transmission distance by three times compared to the previous generation product, making it easily compatible with various card reading devices.
• Frequency Band: From 125KHz to 13.56MHz frequency band, the R4 ring can simulate encryption cards or cards with multiple format standards
