Description

RFID结合全息标签的贴纸
技术领域
本发明涉及一种防伪贴纸， 尤指一种射频辨识标签的天线凸露在全息防伪标签 的外围， 可大幅提高天线的收发效果， 使组成的标签兼具有全息防伪及射频辨 识溯源便于追踪管理的效果的 RFID结合全息标签的贴纸。
背景技术
全息防伪标签， 即表面具有镭射全像微结构纹路的蒸镀薄膜， 如猫眼、 透镜、 全息、 浮影等， 其可利用光线干涉， 产生七彩颜色， 图案明显， 色彩斑斓亮丽 ， 虹光效果佳， 易于辨识， 且无法通过影印或印刷的方式复制， 因而成为普遍 的防伪措施， 被广泛地应用于各式精品、 医药、 烟酒、 食品、 化妆品、 电子行 业的优质商标、 有价证券、 信用卡及高级工艺品等。
[0003] 而射频辨识标签 (Radio Frequency IDentification, 缩写： RFID) ， 为一种非接 触式的辨识标签， 可用来记载产品出处、 制造过程、 物流质量， 以进行各项溯 源追踪管理， 其标签即便被物品遮盖不见， 无论是在手提箱里， 纸箱里， 盒子 里等， 射频标签只要靠近或经过读取器都可以被迅速读取， 而且读取机可以一 次同吋读取上百个射频标签。 另外， 在射频辨识标签的芯片中也可利用特殊的 编码来达到防伪功能。 故防伪技术同样被广泛应用在上述相关精品， 甚至当成 身份证、 通行证、 钞票、 电子车票、 电子收费系统及宠物芯片等。
技术问题
[0004] 理论上， 若将全息防伪标签及射频辨识标签两者相叠共享， 使其兼具有全息防 伪及溯源追踪双重效果应该会更好， 但实际上其效果并不如预期。 主要是因为 射频辨识标签使用吋需要用到天线， 而当全息防伪标签叠在射频辨识标签上共 享吋， 全息防伪标签的金属反射层即会将射频辨识标签的天线给盖住， 影响其 正常收发功能， 使信号反应相对变弱， 辨识效果不佳容易造成失误。
[0005] 现有常见的全息防伪标签规格为 1.7cmxl.7cm〜2cmx2cm之间， 面积大小有限 ， 若要克服前述缺点， 在其与射频辨识标签两者相叠共享吋， 基材层 PET就必须 添加铁氧体吸波材料， 使射频辨识标签的天线能收发信号， 正常使用， 但如此 一来， 物料成本和整体厚度即会大幅增加， 为其主要缺点。
问题的解决方案
技术解决方案
