Now, online gifts through mobile vouchers are more preferred than offline gifts. It has the advantage of maximizing positive emotions, such as the thrill of sudden exchange without physical restrictions, as well as being able to use them whenever you want, such as cash.
Giftletter is a global mobile exchange ticket issuer. However, after the issuance and product exchange process, there are several limitations in the used transaction process of the exchange ticket between individuals.
1 It cannot be guaranteed that the voucher sold by Customer A to Customer B is a valid voucher.
2 When customer A sends the voucher to customer B for sale, it is a "replicated" voucher on customer A's smartphone and is not completely transferred.
3 An error occurs in the collection of big data due to a mismatch between the subject (Customer A) who purchased the exchange ticket and the subject (Customer B) who actually used the exchange ticket.
4 In order to minimize the risk of problems 1 and 2, it is inevitable to share personal information between individual sellers and individual buyers. (Contact number, real name account, SNS account, etc.)
1 Validation of the coupon is conducted before Couponbay brokers used mobile exchange rights transactions.
2 According to the terms and conditions of personal information use agreed during the Couponbay membership process, a quick response is possible in the event of legal problems including fraud.
3 In the process of collecting big data, the transfer of exchange tickets is reflected, enabling more accurate consumption trend analysis, and new data can be derived by comparing the sales and used transactions of exchange tickets.
4 It is unnecessary to provide and expose personal information when paying using virtual assets, including CUP tokens.
5 All transaction details are recorded on the blockchain server, which is safe from forgery and alteration.
It is a sufficient solution to the various problems and limitations arising from the existing mobile exchange ticket distribution method.
