RFIDSU Flag Tag UHF RFID Labels provide a cost-effective alternative to expensive liquid-resistant and on-metal RFID tags.
Traditional RFID inlays struggle when placed near liquids or metal surfaces, requiring specialized (and costly) antenna designs. Our flag-type structure solves this problem through physical design rather than expensive engineering — the raised flag shape keeps the inlay away from interfering surfaces while maintaining reliable read performance.
This makes Flag Tags ideal for budget-conscious projects that need reliable RFID performance in challenging environments: beverage bottles, metallic packaging, pharmaceutical containers, and retail products with foil liners.
Available in multiple standard sizes with popular chip options including NXP UCODE 9 and Impinj M730.

Frequently Asked Questions
What makes Flag Tags different from regular RFID labels?
Flag Tags use a raised flag structure to keep the inlay away from liquids and metal surfaces. This provides reliable performance in challenging environments without the high cost of specialized liquid-resistant or on-metal tags.
Are Flag Tags as effective as expensive liquid-resistant tags?
For most applications, yes. While specialized tags may offer slightly better performance in extreme conditions, Flag Tags provide excellent reliability at a fraction of the cost — making them ideal for budget-conscious projects.
Can Flag Tags work directly on metal surfaces?
Flag Tags perform well near metal surfaces by keeping the inlay elevated. For direct metal contact applications, we recommend dedicated on-metal tags.
What chip should I choose?
NXP UCODE 9 and Impinj M730 are the most popular choices due to their excellent sensitivity and reliable performance in challenging environments.
What is the minimum order quantity?
Standard MOQ is 10,000 pcs per size. Samples are available for testing before mass production.
