The Spanish PLF (Passenger Locator Form) is an online health declaration that must be filled out by every incoming visitor to Spain who wishes to enter the country by plane or ferry, including travelers staying in Spain for transit-related reasons. Thus, the Formulairo de Control Sanitario (FCS) is a health control form that can be completed entirely online before entering Spain. Filling and submitting the form results in a unique QR code generated for each traveler.
The QR code serves as a confirmation of completion of the Spanish health form and will be checked by the Spanish health authorities upon arrival. That is why it's best to have the QR code in both paper format and electronic format to make sure you'll be able to present it.
