An NFC requirement should identify the tag, the data it carries and the application action that follows a tap. “NFC supported” does not specify the complete workflow, tag compatibility or how a proposed case affects practical use.
Write a small interface record
| Item | What to specify |
|---|---|
| Tag | Exact type and a representative sample |
| Data | Format, identifier and meaning within the work system |
| App | Package, version and expected response |
| Handling | Phone case, workwear and normal tap position |
| Error | What should happen with an unknown or repeated tag |
Android's NFC documentation describes tag data handling and NDEF messages. Software must interpret the data and perform the intended action. Reading a tag is not the same as completing an inventory or access transaction.
Use the production-intended arrangement
The current R4-T listing includes NFC. This is a platform feature to evaluate, not a promise that every tag, application or ODM antenna arrangement is supported.
Ask the supplier to identify the documented tap area for the chosen configuration. Do not specify an antenna location from an advertising image. If the project changes a housing or adds a case, include that arrangement in the agreed usability check.
Agree observable acceptance steps
- Use a non-production tag and test account.
- Tap in the documented position with the intended case fitted.
- Verify the resolved identifier and resulting app screen.
- Check an unknown tag and a repeated tap without creating unintended transactions.
- Record the exact phone, app and tag configuration used.
Keep customization questions explicit
If a project needs a different tag technology, tap location or application launch, ask whether the platform can meet that requirement. Do not treat a desired function as an available ODM option before the supplier confirms it.
Send Phonemax the interface record and tag samples to discuss feasibility and evaluation. This guide supplies a proposed acceptance plan, not an existing integration or environmental test result.
