This lack of performance has forced users to abandon Shelf Readers and Portal Readers in favor of mobile readers. But, when it comes to mobile readers, barcode has a huge advantage over RFID because barcode readers are the size of a cell phone, and battery life is measured in days. RFID readers are more that 10 times larger, heavy, and have a battery life measured in hours.
Add to this the fact that item level tagging, for retail chains, is now all but abandoned. This is primarily due to the lack of performance. The five cent tag is unachievable without the volume demand of item level tagging. Barcode tags, on the other hand, continue to be relatively free.
For some time now, hand-held mobile applications of RFID have taken center stage. Automation and "The Internet of Things" are hardly mentioned. Soon, RFID in the retail supply chain will be a thing of the past. It just cannot compete against the established barcode technology. I think Wal-Mart is just going through the motions hoping somehow to salvage some of their large investment in RFID. In my opinion they will not succeed. No one can afford to follow in their footsteps.

這項功能不佳的問題迫使使用者放棄架位讀取器和閘口讀取器轉而使用手提式讀取器. 但是 對於手提式讀取器而言; 條碼系統就比無線射頻辨識系統具有非常高的優勢因為條碼辨識機只有手機的大小而且電池可以用上好幾天. 無線射頻辨識系統讀取機比條碼辨識機要大十倍以上, 笨重而且電池只能使用幾個小時.
除只之外, 事實上項目標示牌在零售鏈早就都被幈棄不用了. 這是因為標示牌真的不好用. 預期成本要在5分錢以下的標示牌除非在大量製造標示牌的情況下根本不可能實現. 比較起來, 條碼; 基本上成本低到幾乎是免費.
在目前來說, 手提式無線射頻辨識系統機是所有應用的中心. 很少有人再去提自動化和”網路應用”等等的事. 不久的將來, 無線射頻辨識系統在零售鏈就會成為歷史文物. 無線射頻辨識系統真的是完全無法與長久使用的條碼系統競爭. 我個人認為渥瑪只是在情緒過渡時期寄望看看有甚麼辦法可以挽救一部份他們在無線射頻辨識系統所下的巨額投資. 我的看法是他們不會成功的. 沒有人可以承受跟著他們腳步使用無線射頻辨識系統所蒙受的損失.
