What sort of israeli tag is this?

I have this little silver pendant type thing that I found that has an oval with arabic written in it on the top and a star of david beneath it. Its almost zipper-pull shaped and about the same size as one. Does anyone know what this pendant may be? A friend said something about INF or IBF or something like that but when i looked up army id tags there wasn't anything like that. So I'm wondering what exactly it may be. I'm assuming its israeli because of the star of david and arabic. Anyone have any ideas?
