RFID Journal Staff asked 4 years ago I am working on a project for a water company and am curious which tag I should use to track gallon-sized bottles. The system must take into consideration the sterilization process, which involves steam and high pressure. What specific tag would work for my application?

Kamal,
I cannot offer a single specific tag that would work for your application, since the right tag to use would depend on a number of factors, including the material of which the bottles were made. Glass, plastic and metal all have different dielectric constants and would detune tag santenna in different ways.
If the bottles were made of plastic, which seems the most likely scenario, then tag location would also be important. If there were a spot near the neck of each bottle where a tag could be placed, then you would not require a special tag tuned to function near water—you would simply need a tag designed to withstand sterilization.
I would suggest reaching out to Avery Dennison, Smartrac, Invengo or any other large RFID tag provider to find out if they can provide a tag that would work for your particular application. I suggest you include images of the bottles when you contact these companies, as that would make it easier for them to assist you.
