So what's the risk? Merchant's risk exposure levels relating to customer pay options-

Payment Instrument General Fraud Chargebacks and Customer Fraud Customer Security Risk Score Level
Credit Cards High Probability- for both Customer and Merchant:
1) Anyone with access to the card details can use it to commit fraud;
2) Any customer just have to phone their bank to make a chargeback, easy as that to get their money back and merchant has to pay

2 Key risks apply:
1) International payments show high customer fraud. Customer typically receives the order, then charges it back aferwards knowing very well the merchant will not litigate. (*merchant looses the payment, the merchandise and must pay the banks penalty fee)
2) Merchant looses the account once chargeback rate goes over 1%(master) or 2%(visa)
Customer has to disclose personal and card secure data, exposing it for high probability of online fraud by any 3rd party with access to it 3
eChecks Low Probability
(has an e-signature feature and phone
verification system)
Not as likely as with credit cards due to your own MID, e-signature feature and phone verification system Verification phone calls placed to customers to confirm and verify the payments before it gets approved, eliminates any 3rd party fraud attempts 1
Cash Vouchers Very Low Probability None Very secure. No risk.
No secure details disclosed by customer
0

Instant Bank Payments (from your own bank)
Very Low Probability None
(only where a fraud case was made by customer bank)
Very secure. No risk.
Customer uses their normal internet banking to send payments. No secure details disclosed by customer!
0

Score: 3= very high risk | 1= low risk | 0= virtually no risk
