What are metadata inquiries and why do they matter?
Metadata inquiries let you retrieve comprehensive card and issuing-bank information from a PAN, a PCI token, or a network token – without exposing the underlying sensitive data. Typical uses include displaying card brand and last four digits, validating a card, making routing decisions (for example, sending a transaction to the acquirer with the best rate for that issuer), and enriching analytics.
It's an add-on feature that turns vaulted data into actionable signal while keeping it protected.
