| Summary | 0010217: WTID in New Zealand Bank Transfers | ||||
| Description | In New Zealand a Bank Transfer has three fields that can be modified by the sender: Field Max Length Particulars 12 chars Code 12 chars Reference 12 chars The current WTID of 32 characters does not fit into a single field... I suppose it could be split up over the three fields but not sure if that would actually work with the exchange.... Might be a banking API integration question that takes the three fields and plugs them together to recreate the WTID? | ||||

Yes, the banking API integration should take care of it. Similarly, when the wallets render the wire transfer instructions, the NZ wire method should simply instruct the wallet UIs to break up the 32-bytes into the respective groups. But, what is more concerning, is that you only have 3x12 characters. The WTID is actually 53! (32 in binary!). Are you sure there are no other meta-data fields available users could set? |
|
|
Yes, only those three tiny fields are available to be used for custom things by NZ people doing bank transfers... No idea why that is though.... We enter the recipient, the bank account numbers, the amount and those three fields when doing a bank transfer... Nothing else is available for Users in NZ |

Ok, we think it might be OK (=safe enough) to change our code to accept a 128-bit hash instead of the 256 bit public key (as an option, in the future). This will be a non-trivial change, so please don't expect it overnight (or this year). |
