Just store ONE swipe.
If the punter swipes again prior to the buffer being read (which at worst should only be a couple of seconds away anyway), then the latest swipe simply replaces the previous one.
Card readers usually have a status LED. Use this to differentiate between a 'WAIT - your swipe is being processed' or a 'FAILED/REJECTED swipe'.

I had kind of hoped that would be the response. Thank you...will do!
BTW the combination of your magcard code and the $1 magreaders are working out well. (www.allelectronics.com)

Second-hand or not, $1 for a reader isn't bad going.
You know that code reads the Credit-Card info from the mag-strip?... So your Door Access automatically debits their card? Great idea! Gotta nail one to the Men's room door for a giggle...
I was going to start a competition for a bottle of Champage... can anybody swipe a Card thru a reader so fast that my code couldn't catch it... but I drunk it instead...

The $1 unit is used however they do have a new $5 unit.
I have been able to swipe to quickly but hey who is counting
