There seams to be different opinions, on this forum, whether the 6131 NFC supports the ISO14443B standard.
According to the "Nokia 6131 NFC Technical product specification" it supports NFC Forum type 4 tags which is based on 14443A/B.
So, my assumption is that ISO 14443B is supported.
I know that the NFC radio front-end (HW) is based on the NXP PN512 chip which also supports 14443A/B, but I have no information about the 6131 NFC firmware.
Could Nokia clarify this, does the phone support the 14443B standard?
Are there any known problems with 14443B implementation in the 6131 NFC?
