"Bat" is a technology that uses sound waves or ultrasonic waves to realize close-range non-contact data communication. It is also a non-contact data transmission technology, which can be used for short-distance non-contact data communication between mobile devices (such as mobile phones, PDA, PAD), consumer electronic products, PCs and intelligent control tools. "Bat" provides a complete, safe, reliable and effective collection of technologies, and has been successfully applied to Mo Bao's e-commerce platform Rubik's Cube and Mo Bao's offline payment by mobile phone, allowing consumers to fully experience the fashionable and convenient door-to-door service based on mobile phones.

The mobile phone doesn't need to be activated, let alone buy a card. As long as you download the client of Mo Rubik's Cube and open bat, you can realize near-field payment.
