Hi @mifaresdk,
The customer can only show his card in enterance. There is no out. My quesiton was confusing. I mean; 1 services assign to a card A customer. And If customer try to get services for his/her companion the card must be decline for at least 6 hours or 24 hours.
So you mean in first time I have to write a entery date and time into the card. Than in a few second time If customer wants to use his/her card for companion the terminal will read the card enetery date and prosses the info. Than I should also write a usege into the card. So if the usege is 1 and date time is now terminal will decline second entery at the same time for his/her companion. Am I right?
Kind Regards
