BARcode

條形碼(BARcode)是將寬度不等的多個黑條和空白,按照一定的編碼規則排列,用以表達一組信息的圖形標識符。常見的條形碼是由反射率相差很大的黑條(簡稱條)和白條(簡稱空)排成的平行線圖案。條形碼可以標出物品的生產國、制造廠家、商品名稱、生產日期、圖書分類號、郵件起止地點、類別、日期等許多信息,因而在商品流通、圖書管理、郵政管理、銀行系統等許多領域都得到廣泛的應用[1]。

    Identification is pervasive nowadays in daily life due to many complicated activities such as bank and library card reading, asset tracking, toll collecting, restricted access to sensitive data and procedures and target identification. This kind of task can be realized by passwords, bio- metric data such as fingerprints, BARcode, optical character recognition, smart cards and radar. Radiofrequencyidentification(RFID)isatechniquetoidentifyobjectsbyusingradiosystems. It is a contactless, usually short distance, wireless data transmission and reception technique for identification of objects. An RFID system consists of two components: the tag (also called transponder) and the reader (also called interrogator).
