Therese's comment: the solution based on an iPhone case which contains all the add-on payment apps (code bar scanner, swipe and EMV Card reader, signature and card pin entry...) seems quite complete and very similar to Ingenico's iSMP mobile POS http://www.ingenico.com/zee_uploads/all/all/gallery_gallery/2608/ismp-datasheet.pdf

It would be most interesting to know how the total cost of ownership of these systems compares with services a la SQuare and PayPal.
