The Central Bank of São Tomé and Príncipe establishes this Permanent Application Standard to uniformly regulate check specifications, mandating precise dimensions (85 x 150 mm), standardized optical line formatting, security paper properties, and strict quality control procedures for all domestic Credit Institutions. The regulation dictates front and back configurations, mandatory text placement, OCR-B character printing at 10 characters per inch, and anti-fraud ink requirements to guarantee seamless automated payment processing. Non-compliant checks face potential suspension or surcharge penalties, while newly issued models require prior Central Bank approval within a 15-day review window.
