Description

Financial POS voice prompting device and phonetic prompt method thereof

Technical field

What the present invention relates to is a kind of voice prompting device, more particularly, the present invention relates to a kind of financial POS voice prompting device and phonetic prompt method thereof.

Background technology

Financial POS (EFT-POS:Electronics Funds Transfer at Point Of Sale, EFT (Electronic Funds Transfer) point of sales terminal) as a kind of financial transaction terminal, has been widely used in all trades and professions.2002, People's Bank of China has set up bank card line-crossing processing tissue---after the China UnionPay Co., Ltd, the bank card industry has presented more and more prosperous good momentum, and market lays the quantity of financial POS terminal and the situation that the bank card business dealing amount of money has occurred rapidly, continuously, increased substantially.Each merchant bank and proficient service tissue to be received the simple substance amount and are reduced errors in order to improve, when strengthening daily POS professional knowledge of cashier and skilled operation technical training, also on the backstage, communication, technical numerous optimized Measures of having taked such as print, reduce as far as possible and avoid misoperation and technical failure to give the cashier, the unit of accepting, bank's (specialized tissue), the holder brings unnecessary loss, as hold and operate the contest of financial POS terminal cashier knowledge, POS is printed with big font with the amount of money on the bar, increase measures such as fault explanation and disposal route, reduced wrong generation to a certain extent.But along with the holder with being multiplied of card business amount, and the POS terminal lays the quickening of speed, the probability that various mistake takes place the POS terminal still is in rising tendency.The problem that exists in the financial POS terminal operation mainly contains following several:

1. amount of money input error and often produce irremediable loss.

Cause the main cause of amount of money input error to be: the input of the amount of money on the current financial POS terminal screen and our normal thinking writing style differ to.People's thinking and writing style are to write from left to right, and the POS terminal is to insert from right to left, and radix point generates automatically, generation automatically (unit of input digit is for dividing) is divided at just first angle, when causing the cashier to operate the POS terminal input amount of money, often 0 go wrong owing to importing one or two less, consume 170 yuan as the holder, if the cashier is according to daily thinking habit, input digit 170 on the POS terminal, and the amount of money of actual input is 1.70 yuan on that POS terminal, and reality is received 168.30 yuan of holder's amount of money less, the correct amount of money should import 17000, and POS could go up 170.00 yuan of real deducts from the cardholder account.The whole nation lays more than 70 ten thousand at financial POS terminal now, if Change All amount of money input pattern, its input will be an astronomical figure, add that most people have been accustomed to this input mode, so can only continue to continue to use current input mode.Now bank of issue's card quantity is near 1,000,000,000 in China, and wherein 95% is debit card, in case occur loading error very difficulty retrieve a loss, particularly the inter-bank business increases, the recovery probability of successful is littler.The frequent appearance of shortage of money phenomenon brings unnecessary loss on the one hand cashier or unit, has hit the enthusiasm of their receiving bank's card on the other hand.This problem has become restriction and has accepted the very important key factor that market is built.

2. error code is directly perceived inadequately, has influenced the service efficiency of financial POS terminal.

The financial POS terminal in use, various wrong phenomenons often appear for various reasons, software error is arranged, hard error is arranged, transaction errors is arranged, the main frame mistake is arranged, in order to save the POS terminal storage space, three of whole uses of these error messages or two digits are represented.The POS terminal mainly is installed in trade company, is responsible for operation and use by the cashier of trade company, under the prerequisite that current POS terminal is popularized inadequately very much, wants to make the cashier to remember a large amount of error message sign indicating numbers and the represented meaning of each message code, is very unpractical.Therefore, when the POS terminal in process of exchange, such and such error message appears and after, the cashier can only notify and wait for that the professional person handles, and has so not only increased the maintenance cost of POS terminal, and has directly had influence on the service efficiency of POS terminal.

3. frequent training has increased the operation cost of bank and proficient service mechanism.

The cashier in market is not only flowed frequent between the inside, and inside and outside interchange dynamics is also very big, this leaves the post for a certain reason with regard to the cashier who has caused firm training, new cashier bank and specialized acquirer must give training again again, sometimes refuse to use bank card because of training the untimely cashier of causing, sometimes because train once that the cashier does not grasp or using skill on top of, cause the cashier dare not receiving bank's card.Bank or specialized acquirer are for the number of times that reduces training or avoid training untimely and influence the holder with card, generally all be equipped with operation manual at random, but because the handbook explanation is loaded down with trivial details and directly perceived inadequately, the cashier is kept someone at a respectful distance, the handbook that has since keeping be not good at losing, when really needing and have no way of having looked into.Therefore frequent training has become the heavy burden of bank and proficient service mechanism.

4. the prompting repeatedly to the holder has strengthened cashier's work load.

Trade company is for the safety of cashier and payment for goods, all be that the cashier has set up independent workplace, make and kept certain distance between cashier and payer or the holder, when stamping the card, the cashier finishes when needing the holder to input password, the cashier will point out the holder at every turn, " password input password is arranged, do not have please by the XX key ", circulation comes and goes repeatedly prompting, must increase cashier's work load.

If the problems referred to above can not satisfactorily resolve, be not only problems such as having increased cashier's operation, bank's maintenance, training and holder's time cost, the more important thing is that this problem does not solve will directly influence the fast development of bank card industry.Through conscientious market exploration with to the further investigation of POS terminal applies, the imagination of financial POS voice prompting device has been proposed.This imagination mainly solves: the one, and the dealing money error issues.When importing the amount of money, the cashier need the holder to confirm or Transaction Success when returning, voice prompting device can enter for the dealing money of cashier's input automatically loudly, by cashier and holder the voice amount of money and the amount receivable that enter for are checked, just avoided the generation of few defeated and wrong input phenomenon; The 2nd, the cashier can find and get rid of the fault of POS terminal according to voice suggestion.After transaction errors takes place, voice suggestion

Device restores real failure cause of POS terminal and disposal route automatically according to wrong return code, and the cashier handles simple fault by voice guidance; The 3rd, when fault needed the professional person to reach on-the-spot the eliminating, voice prompting device can enter for out maintaining unit maintenance personal and telephone number automatically, thereby has avoided the cashier to run into the generation of fault phenomenon at a loss as to what to do; The 4th, can train the business operation knowledge of this POS terminal at any time automatically.When the cashier need train, voice prompting device can carry out voice and enter for training item by item according to the function menu of this POS terminal, makes the cashier enjoy the training on operation that the professional person holds whenever and wherever possible.The 5th, can initiatively use the voice suggestion holder to input operation after password and holder input password, the number of times that also can use voice to point out holder's mistake to take place once more.Prompting by voice solves the labour intensity that the cashier points out repeatedly; The 6th, by the friendly prompting of voice, the words as thanks such as " thank you are handed over money to my cashier " and so on help improving the affinity of trade company; The 7th, by exchanging between voice and the cashier, the cashier is worked keep happy mood.
