(as of Nov 03, 2023 18:53:41 UTC – Details)

Feature:
1. Ceramic Material: The R4 ring is made of microcrystalline ceramics, with excellent refractive index and dispersion performance, giving off a unique round luster overall.
2. Nano Characteristics: The nano characteristics of external rigidity and internal flexibility are attributed to the low thermal conductivity of microcrystalline , which gives R4 a warm and jade like touch.
3. 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.
4. Frequency Band: From 125KHz to 13.56MHz frequency band, the R4 ring can simulate encryption cards or cards with multiple format standards
5. NFC Modules: Through the two sets of NFC modules, it is possible to run its built in numerous characteristic cloud services separately. No need to install an app for direct use, and suitable for both for Android and for IOS platforms.

How to Use:
1. IC card module: This module is equivalent to a repeatable read and write IC card, supporting the simulation of 13.56MHz M1 (for Mifare 1) type IC cards;
2. ID card module: This module is equivalent to a repeatable read and write ID card, supporting the simulation of EM type ID cards in the 125KHZ frequency band;
3. NFC module: This module can interact with all for Android phones that support&nb
