Problems solved by technology

However, many smart watches use metal casings. When surrounded by metal casings and with a small internal structural space, higher requirements are placed on the performance of NFC antennas. Therefore, it is generally necessary to increase active amplifier circuits to improve The strength of the NFC antenna signal, resulting in a reduction in the battery life of the smart watch

Abstract

The invention relates to the technical field of wearable equipment, and discloses a watch band, a watch, and a method and a device for controlling air transaction based on NFC (near field communication), which aim at improving the cruising ability of a watch with an intelligent card function. The watch band comprises an insulation watch band body, a circuit board and an NFC antenna, wherein the circuit board and the NFC antenna are positioned in the watch band; a controller is arranged on the circuit board and is used for supporting a non-contact type intelligent card protocol; the NFC antenna is electrically connected with the controller. By adopting the scheme, the watch band has the advantages that the circuit board and the NFC antenna are arranged in the insulation watch band body, the electromagnetic shielding to the NFC antenna by the insulation watch band body is avoided, the arrangement of active amplifying circuits is not needed, the watch band can work without power supply, and the cruising ability of the watch can be improved.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a watch strap, a watch, and an NFC-based air transaction control method and device. Background technique [0002] With the rapid development of science and technology, smart cards have been widely used in people's daily life, such as bus cards, subway cards, access cards, shopping cards, etc., making people's lives more and more convenient. Since the smart card works in a passive environment and relies on near-field sensing to realize functions such as information identification, payment, encryption and decryption, the convenience and practicability are high, but the smart card is also vulnerable to damage and loss. disadvantages. [0003] With the increasing maturity of NFC (Near Field Communication, short-distance wireless communication) technology, in the existing technology, the information identification and payment functions of smart cards are often integrated int...
