QR payload inspector

Read the fields inside a merchant QR and check its checksum.

Runs in your browser. Inputs are not sent to Zennopay or saved. Analytics are disabled on this page.

EMV merchant-presented tag-length-value payloads only. A valid checksum does not confirm merchant identity or payment eligibility.

Decoded fields

Paste a payload or load a fictional example to begin.

Inspection, not payment validation.

This tool checks field boundaries, duplicate tags, nested templates and CRC-16. It does not validate every scheme rule, verify a merchant account or submit a payment.
