ATypical bank debit card, paid in the local currency
- What the card draws on
-
The bank account, in SGD. The amount comes straight out of the account.
- DBS Deducts the amount directly, and the card must be enabled for overseas use first.
- OCBC Says its Visa debit card works for shopping online and overseas.
- UOB Debits the account or places a hold for the amount. The card must be activated before use, and the agreement mentions no separate overseas step.
More detail
The card is issued by a Singapore bank and billed in SGD. DBS, OCBC and UOB charge the same totals.
- Who converts, when and at what rate
-
The card scheme, at authorisation, from JPY to SGD at its own rate. The issuer converts nothing and holds an SGD amount.
- What it costs
-
SGD 3.25 on every SGD 100 converted, on top of the scheme's rate.
- DBS 1.00 percent to the card association and 2.25 percent to the bank, for Visa and Mastercard credit and debit cards alike, on payments made overseas or through overseas-based online merchants, refunds included. These are fees on the SGD amount and not a second conversion.
- OCBC Splits it the same way, 1 percent from the card association and 2.25 percent from the bank.
- UOB States 3.25 percent without a split.
- DBS, with DCC SGD 2.80 on every SGD 100, SGD 1.00 to the scheme and SGD 1.80 to the bank.
More detail
HSBC shows 1.5 percent of its own plus up to 1 percent from Visa.
- The rule that bounds it
-
Visa says its system applies the rate available at authorisation for clearing and settlement, and Mastercard says its rates are specific to the date and time the bank authorises the payment.
More detail
Both fall back to the rate at processing if they cannot apply the authorisation rate.
Visa lets an issuer add a percentage to its rate and requires the issuer to disclose it (rule 1.4.3.2).
Notes on the earns and pays rows
The parties and the order of the cuts follow the card payments piece. Industry practice, and no market's split is quoted. The percentages are DBS fees on the SGD amount, from its foreign transaction fee guide, which gives the same split for debit and credit cards. They are fees and not a second conversion. OCBC's debit fee schedule gives the same 1 percent and 2.25 percent split, and UOB's debit agreement states 3.25 percent as one figure. A debit card has no credit line, so the issuer carries no credit losses and earns no card interest.
