Cultural Tip
In Spanish-speaking countries, just like elsewhere, PINs are a ubiquitous part of daily life for banking and digital security. The use of 'tu' (informal 'your') versus 'su' (formal 'your') often depends on the context of the machine or system. ATMs and payment terminals usually default to the informal 'tu' unless it's a highly formal or public-facing system addressing a general audience.
