Interesting to hear. That doesn't sound good. They should have just kept the old Avantix machines. A lot of the Guards and RPIs who i have spoken to have said that they much preferred using the old Avantix machines.
At my TOC the old Avantix machines needed either complete refurbishment or replacement ,towards the end of their life it was fairly routine to get one which would frequently jam with card stock , the card repayment devices needed replacement and the pda itself was not the best with many of them suffering really poor battery life towards the end .
We now use star mobile , the platform itself has potential to be really good what with being able to use relatively powerful android devices , lightweight , decent battery life and online capability . There are however in my experience using it a few functions in the software which are annoying and some functions which it would be good to see but since its introduction there have been software updates so it definitely is a work in progress and given the urgency with which Avantix needed replacement I can see why it was rolled out when it was . I dont really have a personal opinion on the paper ticket stock , but passengers certainly dont seem to be that keen on it even over a year after star mobile being introduced we still get comments about the tickets , I suppose not helped by the fact that traditional ticket stock is still dispensed from TVM's and booking offices .
