British operator O2 has started a mobile voucher service. It’s mainly a straight service for newspapers…retailers use a Nokia (NYSE: NOK) E50 with built-in scanning software to scan the vouchers and check that each is valid and unique, reducing handling and fraud reports Precision Marketing. It follows an 8-month trial by The Telegraph, The Guardian and The Daily Mail (LSE: DMGT) in Kent, where 160 retailers used 700,000 vouchers in the system. The interesting part is that the Instant Voucher System (IVS) (developed with 2nDimension) service also allows promotional vouchers to be sent directly to people’s mobile phones, which can then be read in the stores with the scanners.
