Hello guys, could anybody help on finding the cheapest android device possible? I need about 50 devices which are going to be used as a QR code readers for my trainers. I have a guy who will write an application form me exactly the one I need. I need to monitor attendence of my clients who comes to outdoor places - trainings. The codes can be just stored in the device and then synchronised with our online system once on wifi. The needs are therefore: camera with autofocus, wifi, android OS. NO need for phone or such.(could be if its cheaper) I dont even need any other apps of feature in the device. I need just my personal QR code reader which I can give to my trainers. I was thinking Ipod Touch 4 (iOS will do as well) but apparently its useless as there is just tap to focus. Also I found Micromax A60 saying it has autofocus but then on some forums I found it has not. WHAT DO I DO? I am searching for it like two months at the moment. Price is right @ about 40-50 dollars. I can also use USED devices as well. Any help? Appreciate every comment. Jakub, Prague, Czech rep.
