Hi, I have an application that will use Android phones and NFC tags. The back of the phone will need to be brought to various NFC tags on a regular basis, say every few minutes. In between the phone will be playing music/podcasts/making calls/whatever, and needs to be secured to the body, either holster or armband or whatever. There won't be any normal pockets available. It is not clear what is the best case style to keep the phone attached to the body, but quickly detachable to bring to the NFC tags, without too much stuff on the back of the phone that would prevent NFC function. My initial thought was a velcro armband and velcro backed case, but I'm not sure velcro would work well in a rugged environment. It seems like the expensive phone might just fall off the velcro armband. Does anyone have ideas for a solution with these features? Pointers to actual products would be great!
