How do you place tags in a shop so they get used?

Where people already stop

A tap requires standing still for a moment, so a tag only works where someone was going to pause anyway.

At the product they have picked up. At the till while waiting. At a display someone leans in to read. In a fitting room.

Not in a walkway, not at an entrance where people are moving, and not anywhere a person would have to step out of the flow to use it.

This is the single largest factor and it costs nothing to get right, because it is a decision about where rather than about what.

Height and angle

Roughly hand height, so a phone arrives naturally without crouching or reaching.

On a face people approach squarely. A tag on a shelf edge that faces the floor, or on the rim of a counter, meets a phone at an angle where coupling is poor.

Not on a vertical face above head height, which is a common choice for visibility and a poor one for use.

And not where using it puts someone in the way, because people will not block an aisle to try something optional.

The surface underneath

Shop fittings are largely metal, and an ordinary tag on metal reads nothing at all rather than reading poorly.

Glass shelving is transparent to the field and adds thickness. Wood and plastic are fine.

Painted board over a metal frame is the trap, since it looks like a good surface and behaves like a bad one.

Test the actual spot before committing, and expect to need on metal tags for most fixtures.

Testing a location

Stand where a customer stands and use it yourself, with a case on your phone, without adjusting your position.

Then ask someone who does not work there to use it while you watch and say nothing. Where they hesitate is the answer.

Try it at the busiest hour, because a location that works in an empty shop can be unusable when three people are standing there.

And check it again after the next reset, since displays move and a tag that was well placed in March can be behind a stack of boxes in April.
