When presenting the UHF card to the uPASS reader it is not detected.

UHF technology has a performance degradation in combination with liquids.

When your hand/fingers are covering the antenna in the card the read range will be affected. The card must be presented without covering of the antenna.

The best way to do this is keep the card between your index finger and thumb. Another method is using the card on a lanyard and hold it away from your body.
