This is the start of three blogs surrounding the topic of magnetic strips on plastic cards. The proposed blog topics are:
What are magnetic strips
The advantages of magnetic strips
The disadvantages of magnetic strips
So, here is the first topic – what are magnetic strips:
To start of I think it is important to mention that we offer one product with magnetic strips, this is the full colour solid plastic 760 micron card. Magnetic strips are often used for loyalty and membership schemes and often as business cards to make them look similar to a credit card.
Magnetic strips are usually positioned on the reverse of a plastic cards at the top (there are a few pictures/photos on our website should you wish to view a visual of this).
Magnetic strips are placed on the plastic cards in the form of magnetic tape. There are two different types of magnetic strip tape which we use, they are called High Coercivity (HICO) or Low Coercivity (LOCO). The Coercivity defines how strong the magnetic field is and how immune the data on the magnetic strip is to damage. This is quite a technical area so I will not dwell on it any further. Most of our customer tend to use a LOCO magnetic strip but if in doubt please check with the company who provided your magnetic strip reader. As a very very rough guide HICO magnetic strips are often black in colour where LOCO ones are brown, please be wary though as this is not always the case. Some magnetic strip readers can read both HICO & LOCO magnetic strips but again if unsure please check with your provider.
The magnetic strip itself has three tracks or lines within it. These tracks are used to record data otherwise known as encoding data. The different tracks can hold different information, this again depends on customer requirements but as a general rule:
Track 1: Alpha numeric (letters & numbers) max characters: 78
Track 2: Numeric max characters: 37
Track 3: Numeric max characters: 103
We can encode on to just one track or multiple tracks if required. Again, If in doubt, as usual, please check with your provider.
We can produce magnetic strips which are encoded or not encoded. The choice is down to individual customers needs. For example some customers ask us to encode a sequential number and they link this number to new members when they join. Other customer have the ability to encode the magnetic strips themselves. Just let us know what you require.
As with any data recoding system you will need a reader (magnetic strip reader in this case) and software to compliment it.
There are vast amounts of information surrounding magnetic strips available on the internet. however I hope that the above provide a basic overview.
As a bit of guidance and summary to this blog, I have put together a few questions regarding magnetic strips, these may be useful to ask customers if you are looking to supply magnetic strip cards / loyalty cards / membership cards for the first time:
1) Do you require a HICO or LOCO magnetic strips?
2) Do you require the magnetic strips to be encoded?
3) If encoding is required, please clarify which track the encoding needs to be on and whether any prefixes are required for your machinery to read/see the magnetic strip.
Hope the above is useful for you.
