Review on ACR1252U USB NFC Reader III by Tiger Carpani

So, to tell the truth, I probably should have figured out how to open the case and add a SAM card, but since despite numerous mentions here on their site and on their site, there is NO documentation on it There are product/tech pdfs on this topic I align those two stars. This is a typical documentation violation that you would expect from a product shipped direct from China. Anyway, I broke open the case and figured the cover would just pop off to reveal the circuit board and card slot inside as there is no external slot. The case is now damaged beyond repair, and it was only at this point that I realized that you could pry it back all the way to the rubber feet to reveal tiny screws that would allow the cover to be easily removed. It could have been a standalone diagram or a link to one of the many websites/docs for that product. It's for development only, so it's fine, but it might be painless. At least the code is well documented.
