Proximity and Magstripe Cards

This article covers details related to card options for clocking in and out. There are three types of cards that can be used with some (not all) of our clocks:

We do supply both prox and mag cards. We do not sell bar code cards or bar code readers, however, bar code readers are compatible with our Z series clocks.

Proximity Cards

The proximity cards allow an employee to initiate their punch on the clock and then wave the card near the clock or card reader instead of entering a PIN. This type of card is supported by the Z11, Z18 and Z14 with the built in proximity reader.


Can We Use Non-SwipeClock Prox Cards with the Time Clock?
Can We Use Our Security Key Cards with the Time Clock?

The FlexClock model Z18 can be connected to any external proximity card reader that supports a Wiegand connection. Although there are hundreds of kinds of proximity card systems, as long as the client can obtain a reader device (such as from their security system vendor) that can output an industry-standard Wiegand signal, it most likely will work with the Z18.

FlexClock models Z11, Z14 and Z18 have a built-in proximity card reader that can read only the proximity cards we supply if no external reader is attached.

Card Number

The proximity cards we sell for use with our Z clocks have a card number just like the magnetic stripe cards. The card number is the left most number (without the leading zeros).



To assign the card to an employee, enter the card number in the Employee Setup > Card Number (1,2,or 3) field.


Verifying the Card Number on the Clock

On the clock press 0 then swipe the card and it should display the card number the clock reads off of it and what needs to be in the Card Number field in Employee Setup. 

Magnetic Stripe Cards

The time clock has two reading heads for the magnetic strips on the back of our cards. The time clocks are programmed by default to read track 2 of the magnetic strip but can be programmed to also/instead read track 1. 

If the client has existing cards they would like to use (perhaps for their security system), or you have the ability to program cards for them in most cases it can work, but you will need to program one of the tracks on the card for our clock to read. Usually what will happen is the company or business that encodes the cards for either the security system or for the time clocks will encode one track for the time clock and one track for the security system. 

Our FlexClock Vx-series product line with magnetic stripe reader can automatically detect the timekeeping data on any of the three standard tracks, and ignore any data it does not recognize.

The tracks that are chosen for either would depend on what track the security system usually needs for it to swipe correctly. If the security system uses track 1 of the card then you should be all set as the time clocks by default read track 2. But if the security system uses track 2 then you would just need to reprogram the clock to read track 1.

About each of our models:

Model 330 can only read track 2 and cannot be changed. (Exception: If the sticker in the upper right corner shaped like an arrow reads "T1 STRIPE" instead of "STRIPE", then this clock can only read track 1 and cannot be changed.)

Model 380 reads track 2 by default, but this can be changed in software release 2.04 or later (currently beta at time of this writing, and must be accessed by downloading with the code "7472".) To change the track, press FUNC + 1, then enter password "87225" (spells "TRACK").

FlexClock reads all 3 tracks simultaneously with every swipe, and automatically selects the track most likely to contain SwipeClock data. No special programming is necessary to select a track on FlexClock.

Encoding Your Own Swipe Cards

You may elect to use a third-party printing company to print your own time cards. You may elect to do this because of certain printer companies who own high-volume card printers, and who can offer very low prices on large orders of identical cards (for example, over 10,000 cards). 

The following is the information required to encode the magnetic stripe to make the cards compatible with SwipeClock product.

Describe the card.
• Dimensions: Standard credit card size (3 3/8" x 2 1/8"). 
• Thickness: 10 to 30 mil plastic (30 mil is recommended, and is the same thickness as normal credit cards). 
• Magnetic Stripe: Hi Co or Lo Co magnetic stripe for ISO/ABA tracks 1 and 2. 
• The card number on the magnetic stripe must be printed as variable data somewhere on the card. 
• For artwork, we recommend a place to write the employee's name on the front of the cards. 
• Keep in mind that the side of the card opposite the magnetic stripe will receive a lot of scratch damage throughout the lifetime of the card. Don't put the employee's name, or any embossed numbers, or anything else important there. 
• Unlike credit cards, we suggest that the magnetic stripe be on the bottom half, rather than the top half, of the card. This way, the employee name goes well at the top of the card without scratch damage. The top of the card is usually the only part of the card that's visible when the card is stored in a wall-mounted card rack. 

Which type of stripe should we use - Hi Co or Lo Co?

SwipeClock readers will read either type, but Hi Co is far more resistant to accidental magnetic damage, worth the extra money compared to the employer's hassle of replacing ruined cards, and should always be used whenever possible. 

Which tracks should be encoded?

SwipeClock readers will read either track 1 or 2 depending on the model, so you should encode both tracks with identical information. Use standard ISO/ABA encoding methods just like bank cards (track 1: 210bpi, track 2: 75bpi). Our VxSeries products can read tracks 1, 2, or 3, and will automatically read all three tracks and select whichever track conforms to our format starting with the number 9622. Our Z12 devices will read all three tracks as well but defaults to track 2. So if using these cards with two different numbers, be sure to add the number for SwipeClock on Track 2.

What data should be encoded on these two tracks?

Each track should have 12 digits encoded. The first four digits are always "9622," this tells the clock that this card is a SwipeClock time card and not something like Visa. The last eight digits are the actual card number, which can be any eight digit number that does not start with a zero. It is OK (though inadvisable) to have duplicate card numbers as long as they're not used in the same client. 
Only the 8 digit card number should actually be printed on the card for the user to read. The system discards the 9622 after validating the card - the client/employee should NEVER see it printed.
Note: if any other length number, besides 8, after the "9622," is used, the card will be unreadable. It must be 8 digits long.

What about "colored" cards (red, blue, etc)?

Colored cards are usually "exception" cards, used when clients who have employees with exceptions to the prompting rules (i.e. managers). If you print these, you usually need very few (less than 10% of your order if you choose to do any at all). For blue cards, add two more digits to the end of the code: "16". (This makes fourteen total digits on the stripe instead of twelve). For red cards, use the digits "32."

Show me some examples.

• Sample regular card number 12345678: 
• Track 1: 962212345678 
• Track 2: 962212345678 
• Sample RED card number 55443322 
• Track 1: 96225544332232 
• Track 2: 96225544332232 

How can I see what's encoded on a card?

A special diagnostic mode is hidden on the Verifone SwipeClock. To get to it, hold down * and 3 at the same time. The screen will display "diagnostics." Press 4, and it will say "swipe card now." Swiping cards through the reader will display the numbers read from the stripe.

Bar Code Cards

Bar codes can often be printed on stickers and taped to any kind of existing cards.

Any of the FlexClock Z-Series clocks can connect to an external barcode reader via RS232 connection. You can get a special barcode reader that mounts to the wall and attaches next to the clock. We do not sell bar code readers, but the RS232 connection is a popular industry standard and shouldn't be difficult to find on the open market.


Z12 Barcode Compatibility

When a barcode is decoded by the clock, it is the barcode format (symbology) that determines what the lines and spaces represent. The clock may not know how to decode certain types of barcodes.

The Z12 with a barcode reader is known to be compatible with the following barcode symbologies:

Code 39 (3 of 9)
Code 25 (Interleaved 2 of 5)
Code 128 (including type A, B, C, and UCC/EAN)

It is not compatible with:

Code 93
MSI/Plessey
