TapPay O2O Mobile Payment Tool
TapPay is an O2O payment technology, enabling your app with payment feature through an easy, hassle-fee SDK. We developed a secure data transfer technology DBST. Unlike NFC, our unique DBST technology is compatible with 95% plus of smartphone and most of the POS system, totally without extra hardware installation required.
DBST (Dual Band Sound Transmission) is an unique near-field technology that is self-developed by Cherri Tech Inc. DBST has three major traits:
- Low hardware requirement
Only requires a cellphone that has a SIM card, sound card, internet capability. Tablets can also be used without NFC function, and will not need to change to an NFC capable SIM card. Lastly, users can avoid the hassle of using their cameras to scan QR codes.
- Security system
Information transmission is through SSL 128 bit encrypted system, TLS 1.2 to ensure the safety of information, and standardized elements that are in compliance with PCI DSS standards.
- Intuitive sensor system
Users would only need to bring their cellphones/ tablets close to the sensor to complete payment process. Sensor distance is about 5 cm, average sensor time is about 1 second. It is an easy to use and intuitive experience. There is no additional procedure required.
