Apparently all the reviewers looking for a NFC chip in this strap are either not reading the product description or reviewing the wrong item.  This is a plain nylon 5-ring Zulu watch strap.  It's NOT SUPPOSED TO have a nfc chip inside.
I have this strap and have used it for 2 years without any problems.  It's thick and seems well made.  As far as other reviewers complaining about frayed ends on the nylon, DUH! its nylon.  That's what happens to nylon webbing.  Just take a lighter or soldering iron and gently melt the ends to seal it up.  It's the same procedure you would use if the band was too long and you cut it to fit.
This is a good strap at a good price. Buy it.
