125 kHz punch hole cards are special 125 kHz RFID cards that can be attached to a strap or other attachment. The hole may be round or oval.

 

These cards are very useful for marking or identifying devices and other objects. If needed, we can print them with a colourful logo and personalize them.

 

Ordinary RFID cards should not be punctured, as the antenna usually runs around the edges of the cards or in a band up to 1 cm from the edge.
