Nearly perfect app

I have built a similar app to this, so I can vouch for the difficulties that come along with dialing in RFID to make it strong and accurate. This app does the job well. It has an inventory feature as well as a locate feature, amongst others.

It does need a few tweaks in my opinion, hence the 4 stars. If these are added, I can change my review to 5 with confidence.

1. It reads tag data in hex, this should be converted ASCII for my purposes. A simple toggle in the settings could allow the user to decide which way they want to see the data.

2. In the locate feature, instead of scroll though tags you have just scanned, you should be able to type in tag data (which in my case would be ASCII). This would allow a user to plug in the ID’s of the missing tags and search for them. It would also be preferable if the user could enter multiple tags at one time and search for them simultaneously.

FYI my app is the Shelf Aware on the apps store. It’s made to work with the Turck Grokker, but the Grokker is very light weight hardware for the amount of tags I’m looking to scan (6000 tags in a 50X50 swift area).

These are my thoughts so far, please feel free to contact me if I’ve been unclear.
