Paytools vs Kanna Mobile

Paytools is an offline payment-engineering workbench for developers, QA engineers, integrators, students, and fintech teams. Decode and inspect common payment-message structures, explore field definitions, convert technical data, and keep essential payment references close at hand. Processing happens locally on your device, so pasted messages and imported files are not uploaded to a server. PAYMENT TOOLS • Inspect ISO 8583 MTIs, bitmaps, and present data elements • Decode and build primary and secondary bitmaps • Parse BER-TLV data and identify common EMV tags • Recognize SWIFT MT blocks and ISO 20022 XML messages • Convert between HEX, ASCII, decimal, binary, and packed BCD • Validate synthetic card numbers with the Luhn algorithm • Compose synthetic Track 2 and ISO-0 PIN-block test data • Use development utilities for XOR and DES odd parity KNOWLEDGE LIBRARY • Search all 128 ISO 8583 data elements • Learn ISO 8583:1987, 1993, and 2003 MTI concepts • Follow authorization from merchant to acquirer, scheme, and issuer • Understand STIP, advice, reversal, clearing, and settlement flows • Review ISO 20022 message families and validation concepts • Study EMV transaction and cryptogram terminology CODES AND FIELDS Search operational response-code references for common ISO profiles, Visa, Mastercard, UnionPay/UPI, 3-D Secure, and gateway HTTP outcomes. Open any ISO field for its purpose, format, and implementation notes, including an expanded guide to DE22 POS Entry Mode. PRIVATE BY DESIGN Paytools has no account requirement and no cloud processing. Use synthetic or appropriately masked test data. Production payment formats and code meanings can vary by network, region, product, and specification release. Paytools is an independent educational and development utility. It is not affiliated with or endorsed by any payment network. Formal certification and production processing require the current authorized specifications, test packs, approved cryptographic systems, and applicable security controls.

Kanna Mobile is a companion for the Kanna desktop app for macOS. It lets you follow and steer coding-agent tasks from your iPhone while the work runs on your Mac. Kanna Mobile requires a Mac running the Kanna desktop app. It is not a standalone coding-agent host, and it does not run agents on your phone. WHAT YOU CAN DO • See every task across your repositories, grouped by status and activity • Open a task and watch its terminal and agent output stream live • Send follow-up instructions when an agent stops and asks a question • Start new tasks against a repository and agent of your choosing • Review diffs and file contents an agent has touched • Get a notification when a task needs you TWO WAYS TO CONNECT On your local network, pair directly with your Mac by scanning a QR code. No account, no sign-up, nothing leaves your network. Away from home, cloud access relays the connection between your phone and your Mac. Cloud access needs a Kanna account and is currently invite-only — request one at kanna.build/support. BUILT FOR PEOPLE RUNNING SEVERAL AGENTS Kanna gives every task its own git worktree, branch, and agent session, then moves it through a workflow: implement, review, pull request. Kanna Mobile is the window into that from wherever you ff before lunch, an agent stuck on a question, a reviewyou want to read on the train. Kanna works with the coding-agent CLIs you already have installed on your Mac. A NOTE ON WHAT YOU'LL SEE Kanna is a developer tool. It displays repository names, branch names, task prompts, and raw terminal output from your own machine. Requires the Kanna desktop app for macOS, available at kanna.build.
