In Cuenca, Ecuador, taxi drivers and small merchants are discovering a surprising financial advantage: QR payment systems like Deuna and JEP that charge little to no transaction fees. Unlike traditional card networks, these local solutions bypass the elaborate international payment infrastructure, offering merchants a cost-effective alternative that feels almost magical to users.

While Visa and Mastercard provide global convenience and fraud protection, their processing fees have steadily increased, creating a significant burden for small businesses. A 4% fee on a $150 sale might seem minor, but it represents 12% of a merchant's profit margin. In Ecuador, where 15% IVA tax is included in prices, merchants effectively pay processing fees on both revenue and tax amounts - a compounding cost that erodes already thin margins.

The contrast with systems like Brazil's Pix is striking. This central bank-backed instant payment network has achieved remarkable adoption, forcing traditional card networks to compete with faster, cheaper alternatives. For merchants juggling rent, wages, and utilities, these percentage points extracted from each transaction have become a tax on survival rather than a minor administrative cost.
