1) A lot of this stuff is experimented with children.  I'm concerned  
that they don't have the information or skills to give informed  
consent or assent.  Especially when the details are 'hidden' and the  
schemes have attractive fripperies (Discount voucher for music etc).

2) Physical contact - with fingers - of the reader seems sub-optimal  
in today's "wash hands" clean society.
