Error reading tags

Seems regardless of the tag type I use (tried with Classic 1K, NTAG213 and NTAG424), I get the following error as soon as I tap it:

I am using a ACR-122U reader. What could be causing this?

get a different reader. See a similar issue: martinpaljak/GlobalPlatformPro#307

Ok thank you! I totally missed the whole wiki section on here. I'll look for a better reader. Thanks so much for developing this!

I got an ACR 1252U-M1 and the application is working perfectly now. Thanks again!
