If I embed a passive tag in an object that undergoes force applications, how much force can the tag withstand?

Shouvik,

A passive transponder is a fairly fragile device. For it to operate properly, the tag antenna and the tag chip must have good connections. Bending, banging and other mistreatment can break the bond and cause the tag not to function. However, many companies provide housing to protect the tag from damage. You need to select a tag that can withstand both the embedding process, which might include high heat that could melt the solder bonding the chip and antenna, and any force applied to the object in which the transponder is embedded.

My suggestion would be to reach out to some of the companies that make tags designed to withstand harsh environments, such as Confidex, Laxcen, Metalcraft, Omni-ID, Omnia, Securatag Assembly Group, Syrma Technology, Tadbik Group, The Tag Factory, Technologies ROI, William Frick and Xerafy. Explain what you are trying to achieve, as well as the amount of heat, pressure and force to which the tag will be subjected, and find out if they have a tag that will meet your needs. I am sure more than one of them will.
