does anyone use chip and pin readers? i noticed that screwfix are doing the payleven reader for £99 and only a 2.8% charge per transaction instead of monthly fees. i thought these look like a good idea as not all customers have (enough) cash on them and would certainly help on emergency call outs. they run through bluetooth via smartphone or tablet and they seem to be compatible with iphone and android but not blackberry, shame as i had my eye on the z10 for xmas 🙁
