親愛的必克英語學員：

由于我們工作的疏忽，導致昨天（5月7日）“每日話題”中的“話題延伸”部分內容出現錯誤。在此，向您表示真誠的歉意！也向為我們反饋錯誤的學員給予真誠感謝!

我們已經組織老師對過往的話題部分進行審核，確認話題延伸內容沒有任何問題，請學員們放心復習與記錄。目前我們已在審核上設置雙層校對，確保今后不再讓類似的問題發(fā)生！

現將原先錯誤與改正過后的內容公布如下：

（1）原來有誤的話題延伸內容：

Evenly on the magnetic card is a plastic film coated with a layer made of magnetic particulate materials. IC card is IC chip is packaged in a small brass plate and mosaics in the plastic card. We are now widely used bank cards belonging to a magnetic card. It gave us the handsome gently stroke to complete payment, eliminating the change, and many other problems. We use bank cards is the process of re-magnetic card swipe machine records heads to read and process. Advantages of magnetic cards are easy to read and write, low in cost, and disadvantages of magnetic cards are easy to wear, easy to other magnetic field interference. So it is best not to take it and mobile phone, key in a Pocket, because the magnetic field causes the magnetic card phone failure, the key will scratch the magnetic stripe. China's second generation ID card is used in the latest IC Card technology, not only can it use non-contact, you can also contact machine readable, the success of the security, confidentiality and non-contact touch in conjunction quickly and easily. Relative to the magnetic card,IC card information is stored in the chip, which makes it less susceptible to interference and damage, the service life is long; while chip capacity is much higher than the magnetic card, has an edge on the storage of personal information. But its shortcomings are obviously, fabrication costs are relatively high, in addition, corrupt or missing cards easily after relative magnetic cards.

There is a plastic film coated with a layer made of magnetic particulate materials on the magnetic card while IC card is IC chip packaged in a small brass plate and mosaics.

We are now widely using bank cards with magnetic stripe.It gave us the handsome gently stroke to complete payment, eliminating many other problems.

Let's check the advantages and disadvantages of the magnetic cards now.

Advantages of magnetic cards are easy information reading and low cost in operation for widely used.

On the other hand, the disadvantages of magnetic cards are easy cloned and interfered by other magnetic field or being damaged .

As a result, never put it together with cell phone or metal stuff such as keys.It would cause phone failure possibly and the keys will scratch the magnetic stripe unexpectedly.

China's second generation ID card is used with the latest IC Card technology,which can provide security,confidentiality and fast information reading by machine.

Compared with magnetic card, IC card information is stored in the chip,preventing possible interference and physical damage,which has the advantages of longer working periods and higher information capacity.However,there is a problem for ID card now we are encountering.That's the cost of fabrication and machine re-new,such as IC card cost and ATM machine re-new adaptable to IC card.That would be a huge number of money for the bank or other business,which is why IC card is still in the slow process of putting in use.

For safety and technology problems,IC card would be definitely necessary instead of magnetic cards. 

再次感謝您對我們工作的理解與支持！

祝學習進步，生活愉快！
