The QR code fields shall be encoded in Tag-Length-Value (TLV) encoded in 64base
Budget: $30 – $250 USD
The QR code fields shall be encoded in Tag-Length-Value (TLV) format with the tag values specified in the “Tag” column of the adjacent table.
● The TLV encoding shall be as follows:
○ Tag: the tag value as mentioned above stored in one byte
[for tags 1 to 5]
○ Length: the length of the byte array resulted from the UTF8 encoding of the field value. The length shall be stored in one byte.
○ Value: the byte array resulting from the UTF8 encoding of the field value.
[for tag 6]
● Length: length of hash (SHA256 ) is 32 bytes
● Value: the byte array constituting the value of the field
