Description

Ink screen mobile phone with payment function

Technical Field

The utility model relates to an intelligence hardware equipment field, more specifically an ink screen cell-phone with payment system.

Background

The electronic ink is a new information display method and technology, like most traditional ink screens, can display on many different media, such as bent plastics, polyester film, paper to cloth, etc., different from traditional paper, the electronic ink screen can display changed images only when electrified, and does not change when not electrified, and the displayed characters and images do not disappear. The electronic ink screen is mainly applied to the electronic book, and along with the development of hardware and software application in recent years, the electronic book can expand more functions, or the electronic screen is directly used for replacing a mobile phone screen, so that some functions on the mobile phone can be transferred to the electronic book. Due to the chip, the electronic book using the android system has very slow internet speed, and is difficult to directly transplant an NFC chip without functions of SIM card telephone, near field communication and the like.
