该RFID标签被用作用于帐户的特定用户的一个唯一的标识。当通过收费站的车辆驱动器，它的驱动程序提示您扫描自己的RFID标签。如果标识（串行标签的数目，即，12字节的数据）相匹配与已经存储在系统中的之一，收费金额是从他的账户中扣除。在此之后，该车辆获取即时访问以驱动通过。

签名鉴别和笔记鉴别。In this paper, the local features obtained from the signature has been used to create the texture image based on the  spatio-temporal correlation matrix. The Gabor wavelets exhibit  desirable characteristics of spatial locality and orientation selectivity, and are optimally localized in the space and frequency  domains. So it has been chosen to extract the Gabor features of  the image. Signature is a small sample point problem and Support vector machine (SVM) is especially fit for two classes’ problem of small sample. The Gabor features vector has been imported to the SVM classifier and the classification result is obtained. The methods proposed in this paper are validated on the  S
