RFID is a way to give physical items an identity that a reader can capture without requiring every item to be handled one at a time. The useful question is where that identity becomes a trusted business event.
01 / FIELD NOTE
Define the identity
A tag carries an identifier that can be associated with an item, carton, asset or container. The identifier is useful only when ownership, packaging level and data mapping are defined.
02 / FIELD NOTE
Understand the read point
A handheld, workstation or fixed installation captures tag data in a physical area. Tag construction, orientation, material and reader setup all affect the result and must be considered together.
03 / FIELD NOTE
Separate observation from event
Reader output is an observation. It becomes useful after the workflow applies timing, location, identity and state rules to create an action such as receiving, counting, handover, location update or exception review.
04 / FIELD NOTE
Map the operating path
Describe what the operator or connected system does before, during and after the read. Include the destination system, event owner, feedback channel and recovery action for a missing, duplicate or unexpected identity.
05 / FIELD NOTE
State the operating limit
RFID does not remove the need for process design. Mixed materials, missed tags, duplicate reads, uncertain ownership and changes in the site or item mix must be covered by testing and exception handling.
06 / FIELD NOTE
Validate the useful question
Start with the item, movement, environment and business action, then test a representative configuration. Retain the observed behavior, system handoff and acceptance evidence instead of relying on a generic technology promise.
Bring your material, movement, target read and system context to a sample or quote request.
