I'd say buy in something third party. Mag stripe has but a short few years
left in it and the next gen terminals require your software to use public
keys to verify transactions, plus the terminals don's use ASCII any more.
Data is all binary. Doesn't something like GOSELL allow you to validate
txns and isn't too expensive. I'm not endorsing anything but pick
something of that ilk. btw. Kev, if I was still in my last job you'd have
an applicant for one of those positions but where I am now I'm back up to my
neck in credit card stuff anyway so I'm content.
