No change with you? No problem! Our shopping trolley chip conveniently solves any shopping trolley with a slot deposit system. To do this, you simply have to put the chip in the shopping cart and remove it again immediately. Here, the shopping trolley detaches from the chain and you can put your Wunderkey with the chip back into your pocket.

The design of the chip has been optimized for installation in the Wunderkey. It disappears almost invisibly in the Wunderkey and can be folded out if necessary. The shopping trolley chip is made of high quality stainless steel and finished with a matt finish.

Dimensions: 46 x 23 x 2 mm
