文章称，二维码标准工作组根据受Visa、Mastercard和银联等国际支付业巨头认可的EMVCo标准制定SG QR标准。为开发SG QR，工作组还将在当地市场纳入主要的二维码支付供应商，包括银联、支付宝、EZi钱包、GrabPay、Liquid Pay、Singtel Dash、Nets等。最近推出二维码支付服务的银联、Nets和Singtel Dash已经承诺，其产品将兼容SG QR标准。
straitstimes：SG QR will ensure maximum choice of payment options
We thank Mr Keith Heah for his feedback on the QR code standard for Singapore (Isn't just one 'standard' QR code system enough?; Nov 23).
SG QR is indeed the "one standard QR code system" that Mr Heah envisages. It will be able to incorporate payment schemes of all current as well as future providers without needing to conform to each of their proprietary specifications.
SG QR will also be able to accept QR payments from international visitors to Singapore and is open to all acquirers.
The acquirer ensures that the merchant receives the payment that the consumer makes through the QR transaction.
SG QR will be progressively rolled out across Singapore next year.
The Nets' QR code allows merchants to display one QR code for consumers to scan for payments via their e-wallets with any of the seven major banks in Singapore.
However, while Nets' QR can be expanded to include other payment schemes, it can only do so with Nets as the acquirer.
While it would have been ideal for all payments providers to use SG QR from the start, doing so would have meant holding back the introduction of QR code payments until the SG QR specifications were ready.
The task force that developed the SG QR standard based it on the global EMVCo specification, which was endorsed by international schemes such as Visa, Mastercard and UnionPay, and finalised only on July 31. The task force then brought in the major issuers of QR payment schemes in Singapore, such as Alipay, EZi Wallet, GrabPay, Liquid Pay, Singtel Dash, UnionPay International and Nets, to develop SG QR.
The Monetary Authority of Singapore and the Infocomm Media Development Authority will be working with payment providers to update their apps prior to the launch of SG QR and ensure a smooth roll-out.
Nets, Singtel Dash and UnionPay International, which launched their QR payments recently, have committed to adopt the SG QR standard when the latter is launched.
With SG QR, consumers and merchants will have a seamless and streamlined e-payment experience, while having maximum choice of payment schemes when making QR payments.
