c# - Getting phone information by NFC pairing -


I am working on an application for a kiosk where I have the NFC pair capabilities for smartphones with 'quick recognition' I want to add.

This Kiosk has an NFC reader attached here What do I want to do here:

  1. As soon as the NFC-enabled smartphone is touching the NFC reader, I want to get the name.

  2. I think there is no proprietary app installed on the device, so it should be something built in. Something like that the smartphone operating system probably supports?

  3. If I can only do this for Android devices - this is good.

    Is there anything like this possible or is the smartphone NFC only to read information from tags? Thanks!

    You are trying to do this, without having the app on such phones without knowing the information . By default, the NFC protocol is designed to not reveal any identifiable information.

    Based on the type of NFC reader (i.e., how does it communicate), your app can do the following:

    • Peer in peer mode Phone (and NFC Reader) in and send an NDEF message with your application-specific (unique) identifier.

    • Operate the phone in reader / writer mode (NFC reader will work in that case in emulation mode, either working as a contact smart card or NFC tag ) And send your application-specific (unique) identifier to that emulated card / tag.

    • Operate the phone in host card emulation mode (and NFC Reader in Reader / Writer mode) and send your application-specific identifier in response to smart card commands. Receive with your NFC Reader Note that this mode is currently only available on some Android 4.4+ devices and Blackberry NFC devices.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
