易宝时 双离线支付技术介绍

雙離綫支付、一個在中國數字貨幣內陌生的詞彙, 但它的重要性卻不比其區塊鏈或加密技術為低。

在中國數字貨幣的江湖裡、更有傳言 “双離不出、誰與爭鋒?”

數字貨幣不應該是在綫支付嗎? 但是現在不但要離綫支付、還要双離綫支付!

中國數字貨幣的目光和一般數字加密貨幣的層次是不一樣的。它的目標是完全代替人民幣、央行規定它必須跟人民幣能在所有的場景使用、包括偏遠地區或地下停車場等無网絡覆蓋地方。双離綫支付是指受款方和付款方都是沒有連上网絡。中國數字貨幣主要目標是一路一帶跨國應用、這些國家的网絡建設还是很落後呢!

當過去廿年全世界努力在發展在線支付技術、如微信支付、支付寶等。双離綫支付、仿佛被遺忘了。

Apple Pay 和Google Pay 在2014年中雄心壯志地推手機錢包、那是真正的双離綫支付。 可是Apple Pay 是封閉式、不支持第三方開發支付應用, 而Google Pay 代表Android OS 則受NFC短距離通訊晶片在手機的普及率過低、不被用家接受。

iBonus Limited 易寶時有限公司、獲香港政府創新基金的支持、花了六年的時間、鍥而不捨地研發應用於智慧城市票務及數字貨幣手機双離綫支付技術, 並於今年七月、獲得了國際知名Juniper Research 智慧城市手機支付金獎。

採用專利的雙二維碼及藍牙技術、唯一能支持所有iOS 和Android OS 手機雙離綫支付、而交易時間在一秒內完成。

於十一月二日、更率先與香港匯豐銀行推出建基於”沙盒”上的中國數字貨幣双離錢支付的演試平台。

這對於香港金融科技及創新業務在大灣區及一路一帶發展的一個重要里程碑。

Offline vs online capabilities

Ease of use will be crucial to the wide-spread adoption of India’s CBDC. For this, it would be necessary that the ‘digital rupee’ has offline functionality. Several countries are exploring the possibility of enabling offline digital currency transactions. The primary medium being explored for offline transactions are smartphones, smart cards, and wearable devices. However, for a country like India, options such as feature phones or other low-cost technologies accessible to a common man should also be considered.

The last mile

To reach the last mile, it is important to consider the devices that people can use for digital rupee transactions. Anything that is ‘digital’ needs to be stored on a digital medium (e.g. laptop, PC, USB drive, phone, etc.). Although smartphones currently show considerable promise for offline transactions, the reality is that, as of December 2019, smartphone penetration stood at less than 40 per cent in India. Smart sim card-based feature phones, smart cards, wearable devices, and other low-cost technologies should be explored as alternatives or even supplemental options.
