Your phone has no label.
There is a reader and he generates the IDs of the emulated tag.
And please tell me even is it possible to do so, telephone the NFC passed a certain UID in place with cryptococal and opened the door of the intercom, if not then why for the answer thanks in advance! - helga_Lebsac commented on June 14th 19 at 20:18
Look in play store app to emulate the card, there is a possibility to predefine the parameters of the map. - marquis_Barro commented on June 14th 19 at 20:21

But I can briefly tell why not, and then I have the problem with the English, unless of course you don't mind - helga_Lebsac commented on June 14th 19 at 20:30
