Stay alert.

Part of keeping your business safe is simply staying vigilant and understanding what makes a transaction suspicious. We’ve prepared a short list to get you started. Contact us immediately if you experience any of these issues. If you suspect a security threat that isn’t on this list, call our helpline immediately or fill out the form at the bottom of this page.

I think a transaction looks suspicious.
From time to time you may run across a suspicious transaction. Common red flags are:

  • A credit or debit card without the appropriate hologram or a card missing an expiration date
  • A card signature that doesn’t match the signature on an ID card
  • A card with an incorrect starting digit (either an American Express starting with 3, a Visa starting with 4, a MasterCard starting with 5 or a Discover starting with 6)
  • A POS displaying one of the following messages: Card Not Accepted, Call, Call Centre, Referrals, Pick Up, or No Match
  • First-time customers who seem distracted, tense, and/or are rushing their purchase(s)

If you experience any of the above, call our helpline and ask for a Code 10 Authorisation to verify the transaction.

I’ve received a suspicious/phishing email.
If an email is unencrypted, then it isn’t secure. You should never include personal or confidential information in an unencrypted email. JCC will never ask you to provide personal details, or login (username or password), bank account or card details through unsolicited emails. Should you receive an email requesting this type of information, don’t reply, click on any links or open any attachments. Forward us the email Προωθήστε μας το μήνυμα here and we’ll investigate.
I’ve received an unsolicited phone call.
From time to time, JCC engages in promotional telephone, mail and email campaigns, but we never ask for account or other personal information. If you do receive an unsolicited phone call that claims to be from JCC requesting personal information, don’t respond. Hang up and verify the phone number by calling the JCC helpline.
I’m concerned that communicating with JCC isn’t safe.
Whether you’re communicating with us by telephone, email or our contact form, our privacy and security policies ensure that your personal information and your confidentiality are protected at all times.
