HiddenTag C.O.P. 应用的评论

Tries to force you to do everything but scan tags, which should be the apps main purpose.

It works

Good app

Very fast

I have to compliment korean brands for using this wonderful app... It really assures that i got a genuine one.. Love u

10 times better than QR code -^ good job!

So I bought 2 horse oil boxes and tried to check for the legitimacy of the products. But no matter how many times I tried on my iPhone 6, it kept saying the HiddenTag system is not stable. I install the app on my other iPad, it still ended up the same way. Here is the thing, how am I supposed to check the tag if something like this happened? Hope the developers will fix this error soon. Thank you.
