Aim: To develop a new Mobile Phone Top Up Technique using the phone Camera as a 2D decoder to directly decode and execute a pre-encoded Mobile Top Up Voucher in the form of a 2D Barcode. Objectives: Generally, hitherto, mobile top up largely in our locality and even in most part of the globe is practised by scratching card or paper-based refill vouchers which reveals valid voucher PINs. This PIN is manually entered by a pre-paid subscriber on his mobile phone using a specific keypad command code sequence, which is a combination of a top up USSD (Unstructured Supplementary Services Data) code- prefix and the valid top up voucher PIN, unique to a mobile phone operator. It has never been convenient for any pre-paid subscriber, who for one reason or the other, could not top up at first attempt and needs to repeat typing these long unique numbers, maybe twice, thrice or even more to successfully top up. Above all, the cost of logistics, storage and distribution of card or paper-based refill vouchers imposes significant overhead costs for all affected mobile operators globally. However, a user can now scan and decode a top up voucher in the form of a QR-Code using a mobile phone with an in-built camera and suitable decoder software for mobile top up purpose. The following are achievable with the introduction of the 2D barcode media, (a) Drastic reduction on overhead cost relating to logistics, storage and distribution of card or paper-based refill vouchers for mobile phone operators, (b) Card or paper-based refill vouchers are replaced by 2D barcodes, thus eliminating the need for card or paper-based refill vouchers, (c) Consolidates operation "Go Green" campaign; an eco-friendly paperless solution, (d) Enhances convenience for subscribers during mobile top up. (e) Provides a new mobile top up experience for subscribers. Commercial Application of this Invention - Besides the conventional application of 2D barcodes in mobile tagging, it has been discovered from experimental procedures that these key elements in my invention also have huge untapped potential and relevance in the telecommunication industry globally. This value- adding innovation also could attract huge commercial benefits because of its cost saving tendencies for major operators and also the convenience it would bring to pre-paid subscribers, if deployed commercially.
