Checklist for merchant at POS
Always compare the signature on the receipt with the one on the card.
Please check the validity period of the card with the embossed dates. If only one date is
given, this represents the date of expiry.
Use the UV security features on credit cards: if no UV security features are visible under
UV light, it is highly probable that the card is a fake.
Always ask the customer to check the amount or at least do this yourself to identify any
keypad input error before the card payment goes through.
Ensure that your customers are able to concentrate on entering their PIN correctly and
without anyone else seeing.
Take all reasonable steps to avoid retaining receipts or card details. Dispose of old
receipts in such a way that the data on them can not come into the possession of third
parties.
Outside hours of business, store your terminal in a safe place.
Do not allow unauthorised persons to have access to the terminal.
If you suspect that the terminal may have been tampered with, please report this
immediately to the police and to B+S.
Ensure that that you keep the merchant copy of the receipt for all card transactions
(purchase, reversal, refund). This is the only record containing important data for any
subsequent charges or for identifying the cardholder.
