Problems solved by technology

Since the area of ​​the mobile payment card is not only smaller than the size of the standard ID-1 contactless smart card, but also the mobile payment card will be affected by the battery of the mobile phone, therefore, the area of ​​the battery used by different models of mobile phones may be different, thus affecting The effect of reading and writing of mobile payment cards is not the same; there is no more effective and general way to reduce the impact of batteries on mobile payment cards for various mobile phones with large structural gaps. Therefore, mobile payment cards are currently used There is a problem of poor contactless performance in mobile payment, that is, the transaction success rate is low or the transaction distance is close, etc.
