Save NFC/RFID keys onto mobile device to be emulated by it

[DarkEnder4583]

Describe the solution you'd like
I would like to request a feature that would allow for NFC/RFID Keys to be saved to a paired mobile device to be emulated later by the mobile device itself (whether by the built in “wallet” applications, or from the Flipper app itself).
 I believe this would allow for a much wider range of usage for these two protocols, such as the ability to use scanned keys when your flipper isn’t around.

Describe alternatives you've considered
I’ve looked for apps to manually enter and emulate NFC keys, but have yet to find an effective/free one I trust.

Additional context
(I’m an iOS user, but I can’t post this in the iOS repository because it doesn’t accept GitHub issues)
According to this website, I know the following NFC types can be emulated by an iPhone (I know many NFC types aren’t able to be emulated by most mobile devices)

• NTAG®
• ICODE®
• FeliCa™
• MIFARE® (Desfire, Plus, Ultralight)
