NUMO QR Code Standards
NUMO national QR code standard for interoperable LYPay payments using Consumer-Presented Mode and Merchant-Presented Mode.
Libya's national QR standard for interoperable digital payments
The NUMO QR Code Standard is the national QR code standard for Libya, developed to enable interoperable and secure digital payments. It supports instant payments through LYPay using both Consumer-Presented Mode — CPM and Merchant-Presented Mode — MPM.
NUMO QR follows EMVCo standards and uses a structured Tag-Length-Value — TLV format to support compatibility across financial systems and payment platforms in Libya.
QR code models
1. Consumer-Presented Mode — CPM
Who generates? Consumers generate the QR code using their bank or wallet application.
Who scans? Merchants or service providers scan the QR to receive payment.
Use case: Primarily P2P — Person-to-Person, and it can also support P2M — Person-to-Merchant payments where the merchant supports it.
Security: QR codes may be static — reusable, or dynamic — transaction-specific.
2. Merchant-Presented Mode — MPM
Who generates? Merchants generate the QR code using POS terminals or banking applications.
Who scans? Consumers scan the QR using their mobile banking or payment application.
Use case: P2M — Person-to-Merchant transactions, commonly used in retail and service environments.
Security: QR codes may be static or dynamic.
NUMO QR code structure
NUMO QR uses a structured TLV format for consistency across participating financial institutions.

Example QR payloads
Static QR example — MPM
Dynamic QR example — CPM
QR payment processing flow
Generate QR — CPM is generated by the consumer; MPM is generated by the merchant or supported acceptance interface.
Scan and parse QR — extract account, institution, amount, and optional metadata according to NUMO rules.
Initiate payment through LYPay — use the decoded QR information in the applicable LYPay funds-transfer flow.
Confirm transaction — complete the LYPay confirmation step and process the returned status.
Receive webhook when asynchronous — use the webhook notification to obtain the final status where applicable.
Integration steps
1. Implement QR generation
Banks should follow NUMO QR encoding rules when generating QR codes.
2. Implement scanning & parsing
Use EMVCo TLV Tag-Length-Value parsing to extract the required fields.
3. Process payments through LYPay
Use the LYPay Funds Transfer API to execute payments using decoded QR information.
4. Handle webhook events
Implement secure webhook processing for transaction-status updates.
5. Apply compliance & security controls
Validate QR contents before processing transactions.
Enforce AML/KYC policies on alias-based transactions.
