why it exists
The longer version
The Singapore sibling of our DuitNow QR library, and written for the same reason: the specification is public, so the implementation should be too.
It generates compliant PayNow QR codes for UEN and mobile proxies, parses inbound codes, and gets the checksum right. Non-profits collecting donations should not be paying a licence fee to print a square.
