# EMV ## Identification EMV is the payment-card specification family governing chip-card data objects, transaction processing, and related interfaces. ## Scanned_20260730-1235 evidence In [[Scanned_20260730-1235|Scanned_20260730-1235]], [[Scanned_20260730-1235#Scanned_20260730-1235.pdf — PDF page 15|page 15]], [[Scanned_20260730-1235#Scanned_20260730-1235.pdf — PDF page 16|page 16]], the notebook preserves tag and transaction-certificate terminology as an example of formal identifier architecture. ## Evidentiary status The notebook occurrence establishes research context, not installation, account ownership, product use, partnership, or administrative control. Further overlays should preserve this distinction. ## Scanned_20260803-1201 overlay PDF page 28 and USPS payment records on pages 41–43 of [[Scanned_20260803-1201]] preserve operational EMV fields including AID, TSI, TC, and TVR. This shifts the collection from abstract standards terminology to printed transaction evidence. The fields document terminal/card processing state for the recorded transaction. They do not reveal the complete issuer decision, account ownership, or authorization history, and credential-equivalent values remain redacted.
