Editor: The author is Jiang hongming, Founder/CEO of huidao Technology in Hangzhou, who previously worked in a hardware company. In this article, Jiang hongming focuses on sonic payment in wireless payment, and introduces three new design schemes of sonic receiver (equivalent to POS function) at the merchant end. We hope to promote the popularization of wireless payment through a more convenient and practical new "POS.ArticleThere are deletions.

To replace card-based payment, mobile payment requires a better user experience in a convenient and secure manner. More discounts must be given to consumers and lower merchant costs. Second, it is necessary to solve the technical cost-first chicken (mobile phone terminal) or egg (mobile phone POS) problem.

 

Square retains users' habits of card swiping, and uses the mobile phone card swiping device as "another low-cost POS machine" to reduce the cost of merchants and achieve a certain success. That is to say, square re-designs the POS machine and implements large-scale near-field payment on mobile phones.

 

Sound Wave payment and magnetic field signature are a technology with a lower overall cost than square. Direct mobile payment does not require a mobile phone card reader, which has a wider future. Which technology first popularized over 10 million POS machines and which technology will get the future of mobile payment.

 

The following focuses on the design of poser for sonic payment.

 

I. Lucky rabbit POS machine

Advantages:

 

1. The positions of all mobile phones are the same. On the top of the screen, all consumers will know how to use the handset, without any ambiguity. To avoid any possible signal interference, the 100% payment is successful. Easy to use.

 

2. When the mobile phone is paid by the mobile phone, the ultrasonic wave does not pass through the body, and the ultrasonic wave is almost completely absorbed by the Yuanbao microphone, which is healthy and safe.

 

3. Basically, the receiver is placed under the ingot. The distance is very close, and a small acoustic emission power is enough.

 

4. microphone down to avoid dust and payment failures.

 

5. Put it down. The user takes out his cell phone from his pocket and naturally goes up. If the user places it down, the user first goes up, then goes down, and adds one more step.

 

6. the cashier has fewer steps and fewer calls for the price (it is very tiring to call for the price all day), print the small ticket, collect the money, and change the value to zero. for sellers, the time for receiving the cash is faster, reduces labor costs, increases efficiency, and increases satisfaction rates.

 

7. Highly ergonomic-compliant, 86 cm cashier, with a small bracket around 15 ~ 100cm, which is about the same as the average waist height of. the user's hand and arm are the most natural, and the most comfortable posture is holding the mobile phone.

 

Ii. Telephone POS machine

 

If you cannot launch an ultrasonic wave from a mobile phone receiver, you will face a serious problem. There are too many mobile phone models and different phone models have different speakers. There are on the back of the mobile phone, there are on the back of the mobile phone, there is on the bottom of the mobile phone; the angle of the mobile phone, the user's height and weight are different, the mobile phone posture is different.

 

Therefore, the POs host must be compatible with various mobile phones, users, and angles and positions. The poser with two separate microphones can receive sound signals from speakers in various locations on the mobile phone. Based on this, the poser can be designed.

 

 

The above microphone can also be made into a 45-degree or horizontally upward distance and angle between the two microphones, guiding and limiting the user to the most comfortable 30 degrees ~ From a 45-degree perspective, you can use your mobile phone to brush your pos. This makes it easy to use and ensures that the 100% payment is successful.

 

The telephone line below the phone can be a USB connection line connected to the cashier.

 

When a user clicks a mobile phone, the phone POS device rings a bell. The old phone ringtones indicate that the payment is successful, and the classical and modern communication is successful. The overall user experience is also good.

 

 

Advantages:

 

1. compatible with various mobile phones and users, 100% payment successful.

2. Low Cost, only 8 ~ 15 RMB.

3. A good user experience can attract users to learn how to change their cash and Card swiping habits.

 

Disadvantages:

 

During mobile payment, the ultrasonic wave passes through the palm of the user's hand. However, if the dual-microphone separation design is not used, but the single-microphone design or dual-microphone combination design, in order to be compatible with the sound wave power of various mobile phones, it will be more unhealthy.

 

3. wired payment

 

NFC converts a signal to a RF signal, a QR code is converted to an optical signal, an ultrasonic wave is converted to a acoustic signal, and a magnetic field signature is converted to a magnetic field signal. Why do we need to transfer the signal instead of directly connecting it to the cash register?

 

So the POS machine is a line! If necessary, simply add a decoder chip and a security chip online, and put the chip on the USB head.

 

 

100% payment successful, 100% no mistaken payment, 100% security. You only pay when you plug in the wire. No one will receive your money when you don't plug in the wire.

 

Just one wire, a low cost mess, one is a headset plug, one is a USB line. If you purchase a large amount of data, the cost is about one dollar. Even if you add a decoder chip, you can make a few cents at most. More than 0.1 billion million merchants nationwide, less than, can send one to each.

 

The best design is that there is no design, and the greatest design is the simplest design. As long as the user accepts the habit of wire insertion, This is the simplest and the best design.

 

This is not the case where the bank card is not flushed. Do you use a mobile phone to replace the square of a bank card? The cost is lower and the popularity should be wider.
