You must let the NIST Catering Manager know as soon as you notice that you have lost your card. A fee of 150 Thai baht will be deducted from your account for each new replacement card, and the card will be loaded with all your remaining credit. Since the credit is stored in the database rather than the card, you will not lose any money.
To temporarily block the use of a card, a request can be made to NIST Catering, or you may set a zero spend limit (0.00) for your child in the Set-Spend-Limit menu, which will prevent further use.
Please note that the replacement card can only be issued during the office hours (see contact information at right).
