Modern feet measuring technology

Well I had a surprise today at Clark's shoe shop at mc Arthur glen shopping outlet. Child friendly and interactive foot measuring! Haven't seen anything like this before!! The shop assistant held an iPad like  tablet devise(I'm a little unsure what this devise was- but I'm going to try and research it) and asked Freya if she wanted to chose 'Jack' or 'Daisy' on the screen there was a character image of a boy and girl, Freya immediately pressed the girl image, the shop assistant then asked her age and encouraged her to find  the correct digit  and press the green tick to confirm. She then slotted the devise in to the machine in which Freya was standing on and hey presto it measured her feet!!!  I managed to take a picture on my ever so handy I phone 5 of my niece having her feet measured. Was very impressed with this technology. From experience when my children were younger getting feet measured can be stressful especially when your 2 year old son can't sit still for longer than 30 seconds  and ends up having a tantrum and refusing to put his foot in the plastic hand held  foot measurer he would have loved getting involved with this new modern technology! Well done Clark's!!
