小弟也曾經接觸過相關產品的開發, 我想針對我所知道的幾點跟先進們分享,$ |7 _' }* C& u% [& i2 T X
8 {* s# @8 _' q; ^% u1 J
1. UHF RFID reader對tag的辨識率目前還無法支援到百分之百(depent on distance), 這是有別於以往barcode的..如果要將tag大範圍的使用於倉儲系統, 我想這點可能還需要市場的接受度跟技術的精進吧.$ L" I0 J9 L% v) s2 H- O
2 K8 _$ F0 q2 b2 O3 a
2. UHF Tag卡片的厚度跟傳統類似悠游卡的比起來, 厚了許多. 普及度也相差甚遠.. Z: i/ Q7 `/ k: H5 q0 U B9 b v% N8 z0 X/ h% z
3. 這種遠距離的tag, 往往會遇到多重讀取的問題. 它所接觸的不是傳統的一對一, 而是可能一對多(one reader vs Multi tag), 或者是多對多. 這些技術在台灣都還沒那麼普及(國外聽說已經有開發,但是定價很高)9 l$ J4 \7 B8 S! {0 i8 G8 A
8 B, p/ q: L) f: c所以小弟的看法是...持續觀望大家對於tag的價位是否可接受, 以及他的應用及創新是否可以達到市場可接受的目標.* Q& ?% O: g h+ w1 P) E
