In order to use NEM's QR at exchanges

Technical Discussion
#1

The QR of NEM I currently know well,

  • V2, type1: Used when displaying your address (message can not be filled)
  • V2, type 2: Used as a bill (remittance amount is a required item)

When depositing on exchanges, the exchange must present the following items at a minimum.

  • Remittance destination address
  • message

Currently, iPhone Wallet has appeared, and the number of people using it on mobile terminals is also increasing.
I am an Android user, so I will report the result of testing on Android below.

Poloniex provides remittance address and message as simple text QR. It can not be read with NEM’s mobile wallet.

Is there a QR format that can be used at exchanges to avoid this kind of situation?
Currently, with the specification of V2, type1, it can not be used as a format displayed by exchanges.

However, V2, type2 is required to input amount of money later by specifying amount to 0, which is the most likely format.
However, there is a problem, encryption of outgoing messages is enabled by default.

 {
   "v":2,
   "type":2,
   "data":{
     "addr":"NBZMQO7ZPBYNBDUR7F75MAKA2S3DHDCIFG775N3D",
     "name":"Poloniex deposit address",
     "msg":"9fb95dd9313bb25f",
     "amount":0
   }
}

Can V2, type2 be controlled by QR code whether to encrypt / not encrypt?
Perhaps if all exchanges are encrypted, we will not accept deposits, so I think that it will be possible to designate here.

Recently I received a lot of contacts if I can not send a mobile wallet to an exchange.
Although I suggested it one month ago, more people are having trouble because I can not send by QR recently.

The QR displayed by Poloniex is simply QR which displays the address and message.
Users are having trouble much time and effort.

Therefore, I want you to create a new exchange format.
I will write below as an example.

{
   "v":2,                                   ←Required
   "type":3,                                ←Required
   "data":{
      "addr":"XXXXXXXXXXXXXXXXXXXXXXXXXX",  ←Required (Poloniex deposit address)
      "name":"Poloniex deposit address",    ←Required
      "msg":"9fb95dd9313bb25f",             ←Required (Poloniex User identifier)
      "crypt":0,                            ←Recuired message is Do not encrypt / encrypt message (Most exchanges NG when encrypted)
      "ammount": 1234567890,                ←Required If the transfer amount has been decided, that value. If you enter here "" or "0"
      "name":"test"                         ←Optional
}

We would like you to consider.

thanks

The json data format is too big data for describe the invoice data. I’d like to use url schema like bitcoin:.
Data other than address should be not required, and it should be optional.

This is the correct approach. It is the nem wallet for request payment and send payment that should read the standard approach like nem:address?amount=10000&name=company&message=invoice&encrypt=0. When sending you should be able to choose to encrypt and be able to enter a message and or name. Receiving should automatically read any of the data and determine if it is encrypted by encrypt=0 to say no. Or just plain decrypt if encrypted.

Also, sending should not be allowed without an amount.
