NFC reader and NFC phone UID

[loicmormont]

Hi,

I have a ACR122 NFC reader and a Nokia 6212 NFC phone. When I try to catch the UID of the
phone with the NFC reader I get 16 hexadecimal number (normal) but if I delete a midlet and upload
it again on the phone this "UID" is different.

1st time get UID: 13FF567DFDC00987.
Delete and upload
2nd time get UID: 13FF567DFEE34190.
Delete and upload
3rd time get UID: 13FF567566DDF678.

Is it normal ? The application running on the reader get another number that the UID ?

Thank in advance.
