SIM CARD brings Containing Gold?

Your mobile phone users who mutually SIM card to find so cheap and pulling out the card discard?
In the cards that have emasnya! The former mobile phone because the old behavior and not sold and removed the light it is contain gold, copper and silver.

Do not believe, a company in Singapore and Japan have already started become members of paramilitary troops Mandiri (cool nickname for scavengers), special old mobile phone SIM card and the person removed. The process of scavengers and a mobile phone SIM card is used with the same skipper scavengers normal: group to submit the results of the processing or mengolahnya to separate the components in the SIM card or mobile phone. From thousands and millions of mobile phone cards that are collected, they can wash kilogram pure gold and tens and even hundreds of kilogram copper, silver, tin and some types again.

From which the gold or metal-metal came? In the circuit in a mobile phone or chip in the SIM card (GSM) or RUIM (CDMA), there is one emasnya. Gold is used because it proved able to channel the flow of electronic more better than copper. Manufacturers or mobile phone SIM card / RUIM not have to reduce or obviate the noble metal content, although in each unit may only amount 1 / 1000 grams.

Now, if successfully collect one million SIM cards used, we can hope to get 1,000 grams or one kilogram pure gold. And if we can analyze a mobile phone used, the more gold, silver and copper that we can get.

Yokohama Metal Co. Ltd., a company scavengers found the reality that the mobile phone and a SIM card is a gold mine that is really great. If one ton of material taken in the gold mine conventional obtained only about 5 grams of gold, a ton of mobile phone dilebur the former can be obtained 30 times, alias 150 grams of gold.

Can Rp 45 million a month

Mandiri gold paramilitary troops from Singapore, and Japan, will enter Indonesia and offers purchase a SIM card used with a price about Rp 100 or Rp 1,000 per phone. They will build a factory to destroy communication tool was, crawl gold, copper and silver that there is.

Let us count the opportunity to wash the gold from the SIM card from some telecommunications operator in the ground water. We start with Telkomsel. This year has 52 million customers. With growth customers average 30% a year, Telkomsel need 200%, even 300% SIM card from the number of customers.

This means, of course there Telkomsel 10.5 million SIM cards that are Greetings so exhausted. Yet again from PT Indosat, Excelcomindo (XL), and eight other wireless communications service.

Total one month can be accrued up to 25 million "card dead". If the per card weighing 2 grams, the number totals around 50 tons. If all was collected and taken logamnya, will be obtained about 25 kilograms of gold a month, and about 100 kg of copper.

With 10,000 mobile phone destroy or used as one ton (assumed to average per mobile phone weighing 100 grams), which means obtained 150 grams of gold, 100 kg of copper and 3 kg of silver. This is outside
plastic, or timahnya which also obtained.

Metal-metal can was sold in the form of ingot (metal raw materials) The price is quite bearable, because berkadar 99.99%, or if 24 carat gold. If the world price of gold is Rp 300,000 per grams, each month from the SIM card and RUIM can be used only fed property at least Rp 7.5 billion. Only the capital of Rp 25 million times 100, the alias of Rp 2.5 billion.

This number will increase revenue by selling copper, which can Rp 1 billion, also from the carton so that dilebur pulp. Ten thousand former mobile phone purchased approximately Rp 10 million will be produce gold worth Rp 45 million, and copper worth Rp 1 billion. This outside sales of silver and tin.

However, in our country, not many phones that are removed. Growth wireless or cellular customers are still comparable to the number of the influx of new mobile phone. Former mobile phone market is more crowded than New mobile phone market, because many members of the community layer gonti particular tend to change phones, switch-plus new mobile phone 3 months held with the new.

In the algorithm Credit Card

In the real world, of course you already know, or at least heard how credit card has been widely accepted in the community. Various shops, and service providers have been receiving payments by using the card credit. Currently in the virtual world (the Internet), payment by credit card also has started widely accepted. Various crimes have been frequently conducted with use this credit card, both in the real world and in the virtual world. However, in this article I will not discuss about the security of credit card, I just discuss a small thing called checks digits on a credit card. This is indeed quite small, but it should be by all people. In the process of payment on the Internet using a credit card, there is a The very process of authentication is required, this is a process for prove that the credit card number is entered correctly, and that is the person who has the right to use the card. This seems easy, a program can be directly connected to the server bank and can be examined directly, but this is certainly enough time, What if the card number was entered wrong type, all connections to the bank server, all search data, and others will be futile. For (slightly) to solve the above problem, credit card numbers have been designed 

in such a way so that the possibility of the initial checks before a number were checked through the bank. These checks are checks combination of digits that are commonly known as algorithms check digit. Check digit algorithms used in the credit card is the check digit Luhn algorithm (Luhn check digit algorithm). 

Check Digit Luhn algorithm 
Check digit algorithm is an algorithm used to check the validity of a digit number based on the Creative-digits. Either application is very common that we find in daily life is a process  importation of goods data that we purchase in the supermarket to buy a small (the still use manual input, do not use the bar code reader). Maybe sometimes you see the cashier sometimes incorrectly entered data so that little error message appears, and then he re-type the code again 
the goods listed in the goods. Have you thought how a computer can know that the numbers are incorrect. The answer is by using a check digits, usually the last digit of the code of goods is the result of mathematical operations to the digit-digits before, so if there is direct input error 
detected, for example, the code is 98876768532 goods, but that is inserted 98876768533 
the computer will consider this data is incorrect. You check digits This does not exist, and each code sequence made goods, computers will be considered correct all data is entered, you may buy a listed Silver Queen chocolate when you buy a brand of chocolate is another. 
To check digit Luhn algorithm, I actually understand the history of less check digits with this algorithm, but the algorithm is used by all the big banks issued credit card (Visa, MasterCard, Amex, Novus, and may still many others). Check digit algorithm is also used in ATM cards,  at least I have noticed an ATM card and BNI bank likely BII bank others also use this method. When introducing the Telkom TeCC (Telkom Calling Card), these algorithms are also used. 

Method check digit is actually simple, need only three steps to to prove whether a card check digit meet the Luhn algorithm, for cards even with the number of digits (eg Visa [16 digits], MasterCard [16 digits], and Novus [16 digit]) do the following: 

1. for each digit in the odd position (I count the digits from the start left with the most digits to the left-1), multiply the value by two, if the results more than 9, subtract the result by 9. Total number of all that it has obtained. 

2. digits for each position on the whole, and the total value of all add the results with the results of the first steps.

3. if the results on the second step is divided out of 10, means the card number legitimate. Not easy, for cards with the odd number of digits (for example, Visa [13 digits], Amex [15 digits]) how to do the same, only the first step is multiplied digits even in the position, and the steps that are both is the digits in the odd position. 

Example: 
If I have a card with the numbers: 
7889-8594-5435-5413 

and I want to know whether this really a valid credit card number or I can not perform the following steps (note the number of digits are 16): 

1) multiplying all the numbers on the two-digit odd and reduce 9 with the result if more than 9, and are This is the digit-digits in the odd position 
D01 = 7 
D03 = 8 
D05 = 8 
D07 = 9 
D09 = 5 
D11 = 3 
D13 = 5 
D15 = 1 
If the operation is done two times and reduce 9 (if more than 9) obtained 
D01 '= 7 x 2 = 14, because it is less the result of the 9 D02' = 14 - 9 = 5 
D03 '= 8 x 2 = 16, because it is less the result of the 9 D02' = 16 - 9 = 7 
D05 '= 8 x 2 = 16, because it is less the result of the 9 D02' = 16 - 9 = 7 
D07 '= 9 x 2 = 18, because it is less the result of the 9 D02' = 18 - 9 = 9 
D09 '= 5 x 2 = 10, because it is less the result of the 9 D02' = 10 - 9 = 1 
D11 '= 3 x 2 = 6, less so from 9 remain 6 
D13 '= 5 x 2 = 10, because it is less the result of the 9 D02' = 10 - 9 = 1 
D15 '= 1 x 2 = 2, less so from 9 fixed 2 

The number of D01, D03 + '+ D05, D07 +' + D09, D11 + '+ D13, D15 +' = 5 + 7 + 7 + 9 + 1 + 6 + 1 + 2 = 38 

2) adding all the digits in the position even 
D02 = 8 
D04 = 9 
D06 = 5 
D08 = 4 
D10 = 4 
D12 = 5 
D14 = 4 
D16 = 3 
Amount = 8 + 9 + 5 + 4 + 4 + 5 + 4 + 3 = 42 
When the results of step 1 and step 2 are obtained 38 + 42 = 80, because 80 out of 10 then divided the number of valid credit card number. It is clear now, check out algorithms digits on a credit card is very easy You can also do produce numbers as a valid card number credit using the program, and he said it could be used for to make credit card fraud is still my own little way with because according to my current inspection is far more strict and almost someone might not pass with only Seeing the number of valid only without expiration date and name of the owner.
