IoT ? IR 4.0 ? Let's get started with LoRaWAN

Internet of Things (IoT) are being famous across the century and in Malaysia, we are begin the transformations initiate by the Malaysia government, moving in Fourth Industrial Revolution (IR 4.0).

What would expected to change is the style of living, working and communicating with families, friends and businesses. Rebuild of business models and employment trends are happening now!

The potential of IoT had gone beyond just simplifying but working with AI, it could use the gathered or pool data for analysis and perform ML to produce something more than we expected in future.

LoRaWAN is which mean for Long Range and it specifically designed with low power working as a MAC protocol for Wide Area Network wirelessly. A deployment of LoRaWAN will allow 'things' to be connected over the internet nationwide. It can facilitate bi-directional communications through electromagnetic waves, secured with end-to-end mechanism, install either portable or permanent to be use freely for decades.

E-Wallet safe?

There are many E- wallet applications that are well known in Malaysia. Like Wechat, AliPay, Razer Pay, GrabPay, touch n Go and more. Soon Malaysia will be a cashless country,  we have to know ways to be more precaution before start using it. Application itself is secured but the one not secured is you. You are the only firewall that is easy to be bypass by the bad guy. This is because there are many baits outsite the world where people are not realizing it.

People always fall into the trap whenever they see huge amount of durian dropping form the sky. But they couldn't remember that durian only drop from the tree. There are many traps in WeChat that happened in China, belows are what they normally do before & after u scan the QR code.


  • Attract user attention with angpao that give benefits.
  • Replacing legitimate merchants’ codes with malevolent copies, fraudsters can gain access to consumers’ data and even raid their bank account.


  • Requiring user to input personal information. (ID number and bank information.)
  • Requiring user to login to your account. (Which actually getting your id and password)
  • Requiring user to enter pin number to receive benefits. (Only Sender required to enter pin number.)
  • Sharing for giveaway or benefits. (User won't lost any but please put it in mind that if someone falled into this trap, it is because of you that shared it.)


  • Keep in mind that Wechat angpao is with a limit of USD$30
  • Do not enter any password / pin
  • Do check into the internet before scanning any QR code having giveaway rewards.
  • Please do take it in mind that before scanning the QR code. Do double check whether there is another piece sticked on top of it. 
  • Do not share any fake benefits, post it in group to rise the awareness instead.
  • Make sure that it redirect you to the correct place.
  • Use Secure QR-Code scanner Kaspersky Qr Scanner

What will happened if scanned a fake QR-Code

These malevolent QR-Codes lead users to malicious websites where users are required to key in personal information. This information is then used to send phishing emails filled with malwares. In the worst case smartphone with viruses transmitted to steal money from the victim's mobile wallet, or ransomware where data is encrypted for a ransom.

OCR API Setup & Deploy with PHP

OCR.Space is a free OCR API which allow parsing images and PDF documents to extract the text in JSON format. Since, it's an API, it could be apply the OCR functions by using GET and POST parameter with any languages in development.

Let's get started by signup an FREE tier OCR.Space API key, this acts as a token for service authentication and initialisation, if no access key is attached in a GET or POST parameter, the return results are usually NULL. Kindly, fill in the signup form at here. Once the request is successful, the API key will be sent to your email inbox.

To use the OCR API, the endpoint for POST had been provided as below and support HTTPS and HTTP protocols. To apply the very basic image parsing via URL and reveal the OCR results, the image below is attached in this demonstration.


Simply append the parameter of "apikey" and "url" at the end of the API address:
The result of OCR parsed will be as below:
As you can see, the parsing will results a JSON output and from what we can observed, we could extract or export the value we required where param at "ParsedText".

To decode the JSON or extract the value out of this structure, we will suggest a PHP scripting as below:

$gateway = '';
$key = 'helloworld'; //input your API KEY, this is test key
$img = '';

$url = $gateway."?"."apikey=".$key."&url=".$img; //establish the url
$data = file_get_contents($url); // fetch content to variable array
$txt = json_decode($data, true); // decode the JSON feed

echo "<h2> LOADED IMAGE </h2>"; //show fetch image

echo "<img border=\"0\" data-original-height=\"739\" data-original-width=\"962\" height=\"306\" width=\"400\" src=\"".$img."\"/>";
echo "<h2> OUTPUT </h2>"; //display image text
echo $txt["ParsedResults"][0]["ParsedText"]; //output the ocr text

Simply deploy the codes and edit the highlighted source with any web server, I'm using APACHE and save it to FILENAME.php 

The result will show as below:

The above demonstration is by default OCR options which the interpretation is in ENGLISH OCR. If you wish to perform an OCR applied with different language, simply modify the parameter of API parsing as below:

Simply append the parameter of "apikey" + "url" "language" at the end of the API address:
Let's try with a image with Chinese characters.


Edit the PHP coding and append with the parameter.
$gateway = '';
$key = 'helloworld'; //input your API KEY, this is test key
$lang = 'chs';

$url = $gateway."?"."apikey=".$key."&url=".$img."&language=".$lang; //establish the url


The results are perfect!

Note that the OCR language parameter's parsing option as below, simply change the $lang parameter with any of the below validated with the text appeared in the parsed image.

Croatian = hrv
Czech = cze
Danish = dan
Dutch = dut
English = eng
Finnish = fin
French = fre
German = ger
Greek = gre
Hungarian = hun
Korean = kor
Italian = ita
Japanese = jpn
Norwegian = nor
Polish = pol
Portuguese = por
Russian = rus
Slovenian = slv
Spanish = spa
Swedish = swe
Turkish = tur

The application of OCR is widely applied in automated processing invalided images to text or to obtain valid values from pictures. The OCR is working in AI, integrated environment or to be a part of a processing node in a system to perform text extraction from provided inputs. Happy Explore & Have a nice day, do leave us any comments and we will reply you shortly.
