在JAVA应用程序中使用RFID阅读器
我需要您的帮助：我必须在java应用程序中使用RFID阅读器阅读卡片。 最后，当我点击“Attribuer numéro RFID”按钮时，它正在读取我的RFID阅读器（型号：OCS ACURW），因此，将十六进制值插入jtextfield文本区域。（首先，jTable获取数据库中每个用户的lastname和firstname。 这是我的项目代码。 如果有人知道当我点击“Attribuer numéro RFID”按钮时我如何阅读RFID阅读器，这将对我帮助很大！ 谢谢！：）在JAVA应用程序中使用RFID阅读器,java,rfid,Java,Rfid,我需要您的帮助：我必须在java应用程序中使用RFID阅读器阅读卡片。 最后，当我点击“Attribuer numéro RFID”按钮时，它正在读取我的RFID阅读器（型号：OCS ACURW），因此，将十六进制值插入jtextfield文本区域。（首先，jTable获取数据库中每个用户的lastname和firstname。 这是我的项目代码。 如果有人知道当我点击“Attribuer numéro RFID”按钮时我如何阅读RFID阅读器，这将对我帮助很大！ 谢谢！：） 这是我的申请代码
