This post is to discuss the advantages of NFC vs QR codes devices. NFC stands for Near Field Communication these are devices such a plastic card you tap next to a device and payment is taken. I will propose that NFC mobile payments using passive devices may be more suitable for mass adoption than Evolution in the short term. An important point to note is that NFC passive device technology is readily available now. We do not need to wait for any more development to take place on Evolution for us to set up an NFC passive device payments POS system. I feel we need to introduce NFC passive device POS payment system in Venezuela to encourage rapid mass adoption there. NFC passive devices may be better than Evolution for non tech savvy people due to the ease of use (simply tap and go). With the NFC passive device the user does not require a smart phone or in fact any phone and it is extremely simple to use even for a technophobic user. A NFC passive device is affordable for anyone and costs just a few USD for each passive NFC device. There is little to no training required to use an NFC passive device. The NFC system proposed would primarily require users to use passive NFC devices. For those who may not be aware an NFC passive device does not require a power source to function. An example of an NFC passive device being used currently is Octopus card in Hong Kong, the contact less plastic card that users tap on a terminal to pay or something similar to the London underground "oyster card" . The passive NFC device derives its energy from the active device when the user touches the NFC active terminal. The user charges the card up with DASH by simply touching the card against an DASH enabled NFC active terminal and entering the amount of money they want to add to the device. This could be undertaken in a shop where the retailer has a modified NFC enabled android phone as the active device. The following content is reposted from this page: https://www.dash.org/forum/threads/...omotion-in-venezuela-and-latin-america.40419/ For mass adoption we need DASH to be so simple to use that granny can use it without any training. Therefore my opinion is that NFC is the way forward for mobile payments in Venezuela and in fact anywhere in the World that wants a simply low tech solution to making payments. My view is NFC is superior to QR for payments in the following respects: See this comparison between NFC and QR by google: In the Youtube video below fast forward to time code 7:47 onwards where they undertake the comparison between NFC and QR code 1. NFC is quicker than QR code. See the google above comparing NFC and QR code: The difference is significant. NFC is considerably faster. 2. NFC passive devices are very cheap e.g. an NFC wristband or card e.g Octopus card (Hong Kong) can be manufactured for around $1 to $2 USD per card this makes a payment system affordable for anyone. No smart phone and in fact no phone of any type is necessary. 3. NFC requires no training. QR code requires some training to use. 4. NFC can work in any light conditions QR code needs good light conditions. 5 NFC is more secure because it has to be in close physical proximity to work and does not require visual identification to register. QR payment code can be easily printed out and stuck over an official QR code. 6. NFC can be used by a Granny (tap and go) with no training. QR code can be confusing for a new user and they also need to open a specific app in order for it to work. 7. NFC does not require the user to have a smart phone. QR code user needs to have a smart phone, with a functional camera. 8. NFC works with a simple tap. QR code focusing is required for it to work as well as a having a smart phone. 9. NFC on a phone does not require opening a specific App. QR code a specific App first needs to be opened. In every respect NFC is more suitable technology than QR code for mobile payments. NFC is easier, cheaper, faster and more secure and does not require training to use. The passive NFC devices can make DASH available and accessible to the masses without the need for any training, wallets, or even Evolution. QR codes and DASH wallets needs people to be trained. NFC payment passive device does not. This means that the barrier to entry for the user is considerably lower when we use NFC compared to QR codes. In essence NFC = Granny Friendly. We do not need Evolution. NFC is already granny friendly. The following is a complete Granny Training Course on how to make payments with DASH using a passive NFC device (e.g. an NFC plastic card loaded with DASH): Steps for making a payment: "Granny go over and tap your card on the device at that shop. Check the amount is correct on the screen. If if it correct tap yes on the screen" . If it is not click Cancel. Well done Granny. You can now make payments with DASH. Steps for charging your card To charge up your card go to any official charge point shop, hand over your Bolivar to the attendant. Tap your card against the recharge device, make sure the amount shown on the charge point screen is the amount you gave to the attendant, minus the small recharge fee that is shown separately and tap YES if it is or CANCEL if it is not. By the way Granny, if you don't feel comfortable going to a authorized charge point I can always charge up your card at any time from my smart phone." END OF GRANNY TRAINING I believe that an NFC payments system in Venezuela is required to accelerate mass adoption there. Stores can sell NFC wristbands or cards at a low cost and the store keepers could charge up their customer's NFC passive devices using a NFC smart phone with DASH in return for receiving Bolivar currency. In return the store keeper could take a small commission for undertaking the recharge for the customer. A modified Android phone as the NFC active terminal offers retailers a low cost entry to this new NFC payments system. Alternatively existing POS systems could be modified to accept an NFC terminal. Then the retailers could sell low cost DASH enabled payments systems. The NFC passive devices could be plastic cards, key rings or even a wristband. These devices will cost just a few USD for the user making it affordable for anyone to use. The best part of all is that we do not need to wait for Evolution release in order for this system to start working. We would simply need a low cost NFC payment system. Some of which we have already sponsored the development of see the link below. The NFC POS system below was designed for making payments at large music events however it can be modified for any retail store. https://www.dashcentral.org/p/Dash-NFC-POS If the teams in Venezuela could consider integration of an NFC POS into their existing POS and provide low cost DASH enabled plastic payment cards we could make DASH payments simple for anyone to use. Here is a demo of an NFC device that DASH treasury has already paid for its development. We could modify this device for a POS for retail use with very little cost: With NFC passive devices the frightening tech would disappear into the background and make payments simple for anyone to use with a simple "Tap and Go".
