NFC at 424kbps: Specify the Transaction, Not a File-Speed Promise

A 424kbps NFC requirement needs to identify the protocol and transaction being evaluated. It should not be presented as measured file-transfer speed on an unspecified phone. This guide verifies no current Phonemax NFC transfer-rate result.

Define the small-data task

Record the tag or peer device, data structure, application and expected outcome. Ask the system provider which radio mode and rate are required. Keep that requirement separate from the time the complete app takes to display or save a result.

  • Use an authorized representative tag or peer device.
  • Confirm the supplier's supported protocol and mode.
  • Run the complete read or write action and inspect the saved data.
  • Record failed attempts, repeated taps and application completion time.

Use general NFC information within its scope

The NFC Forum overview describes several protocols and operating modes. Those technology options are not proof of the negotiated rate or app performance on a particular handset.

Current hardware reference

The R4-T listing confirms NFC. Use the NFC workflow guide to organize acceptance. Retain the exact combination and observations; do not convert a protocol figure into a universal “fast transfer” claim.
