Memory element with radio identification function and portable electronic device

Abstract

The invention discloses a memory element with a radio identification function and a portable electronic device. The memory element with a radio identification function is arranged in the portable electronic device, and comprises a semiconductor packaging component and a magnetic component, wherein the semiconductor packaging component comprises a substrate, a semiconductor chip, an antenna and a packaging colloid, the semiconductor chip is arranged on the substrate, the antenna is arranged on the substrate and electrically connected with the semiconductor chip, and the semiconductor chip is wrapped with the packaging colloid; the magnetic component is arranged on one side of the semiconductor packaging component opposite to the substrate and the antenna, so that the magnetic component and the antenna are separated by the packaging colloid; and the projected area of the magnetic component on the substrate is an area for covering the antenna so as to guide electromagnetic waves emitted by the antenna in a particular direction, therefore, the magnetic force of the antenna in the particular direction is enhanced, so that the magnetic force in the particular direction can penetrate a thicker shell so as to provide sufficient magnetic to enable an induction chip to achieve an effect of induction, and a mobile phone has a password card function.

Description

technical field [0001] The invention relates to a memory element with a wireless identification function, in particular to a memory element with a wireless identification function provided with a magnetic piece and a portable electronic device including the element. Background technique [0002] With the advancement of technology, the demand for electronics in daily life is also increasing, such as: mobile phones, electronic wallets, proximity cards, etc., and in order to meet humanized needs, electronic products tend to be multi-functional, such as: 3G mobile Therefore, the sensing function is integrated on electronic products such as mobile phones, so that the mobile phones have the functions of electronic wallets and pass cards. [0003] see Figure 1A , Figure 1B and figure 2 ,in, Figure 1A for an existing mobile phone1, while Figure 1B It is an existing pass card 2, such as an Easy Card; figure 2 As shown, the access card 2 has a substrate 200, on which a chip ...

Problems solved by technology

However, because the thickness h of the housing 1a of the mobile phone 1 is much greater than the thickness d of the housing 2a of the pass card 2, and because the antenna in the chip with the wireless identification function emits electromagnetic waves in a divergent manner, the It is difficult for the electromagnetic wave of the chip with the wireless identification function to penetrate through the housing 1a of the mobile phone 1 concentratedly, resulting in insufficient magnetic flux penetrating the housing 1a of the mobile phone 1, so that the induction work cannot be effectively performed.
