Merchant VS Consumer Mode: Understanding EMVQR Standards
The EMVQR standard defines two main ways payments are initiated. Understanding the difference is key for developers and business owners in the fintech space.
Merchant-Presented Mode (MPM)
In MPM, the merchant displays a QR code (static or dynamic) and the consumer scans it. This is common in retail and small shops because it requires no expensive hardware from the merchant.
The QR code typically contains the merchant ID and, in dynamic cases, the transaction amount.
Consumer-Presented Mode (CPM)
In CPM, the consumer generates a QR code on their phone, and the merchant scans it. This is often faster and more secure, as the consumer's device generates a one-time token.
This is common in high-traffic environments like supermarkets and public transport turnstiles.
"Both modes have their place. MPM offers low barrier to entry, while CPM offers speed and enhanced security for high-volume environments."
