Shopping cart advice We use authorize.net as a processor, with AuthorizeCim. A little order form pops up at checkout. This order form just doesn't work on some smart phones, so we are considering switching over to an on-site form. Any suggestions on the best way to approach this with aMember? For authorize.net options, in admin I see aim, dpm, and sim. Any suggestions on which one of these would be work best, which is the safest, etc. Also, what are the risks or challenges with using on-site forms like this? Thanks for any clarification or suggestions.
