FAQ - THERMAL REWRITABLE SOLUTION

What exactly is a Thermal Rewritable Solution?

  • The card reader/writer magnetically reads the card’s balance.
  • It thermally prints the transaction.
  • It magnetically updates the card each time the card is inserted.
  • The reader/writer erases the thermally printed transaction (s) at the next use.
  • The card reader/writer can erase the previous transaction or the whole card when it's full, so the card can be used again and again.
  • A card can be erased up to 500 times.
  • The thermal rewritable printed data will only be affected at ove 120℃
  • When it depletes its value, the customer could reload its value.
  • Durability and reusability define the importance of the PET rewritable smart card.

What’s the difference between the various kind of thermal-rewrite cards?

  • Comparing with the obsolete technology - the "silver" card, coated with transparent-opaque layer, our rewritable card offers better text & image quality in terms of image density and contrast ratio.
  • The totally transparent rewritable material offers much greater flexibility on card design and graphics composure.
  • Our design team is professional.   Our design will represent your company with inspiring image and eye-catching simplicity.

How much data can the 3rd Generation Rewrite Card stores?  Is it reliable?

  • Our card contains 3 hidden read/write magnetic tracks for electronic data storage.
  • The coercivity is 1750 Oe. It is hard to be affected or altered by typical magnetic sources and therefore digital
  • data is well protected under most situations. (normally there is 300-650Oe for traditional magnetic cards).
  • To comply with the ISO standard, the 3 readable/writable magnetic tracks stores:
    1. 1st track: 79 characters (characters or numbers)
    2. 2nd track: 40 characters (numbers)
    3. 3rd track: 107 characters (numbers)
  • Electronic data will be processed and stored by the encryption/decryption processes.
  • Afterward, all of the encrypt data can be written into rewrite cards.
  • If there are needs for huge data capacity storage or high data encryption system, clients could be advised to adopt our thermal rewritable smart card products.

How many types of Card Reader/Writer (CRW) are available?

2 types: Stand-alone & POS (Online) Model.

What is their respective characteristics?

  • Standalone type model is capable of 2 operating modes - stand-alone & POS.
  • standalone type model works like as a mini computer.
  • Built-in keypad to perform various commands and functions.
  • It can be operated with the built-in and customized software program in order to fulfill different client’s needs.
  • It is simple and configurable.
  • Standalone type model is especially suitable for point card, game card or bonus card.
  • And online type model can only be used online with a PC connected.
  • Both of them can support PET thermal card.

How much data can be stored in the standalone model? Can the data be taken away for further processing?

  • CRW in standalone type model contains 4Mbit static memory SRAM.
  • Assuming each transaction requires 256bit storage, 10,000 transactions can be recorded.
  • Standalone model has one or two serial port (9-pin RS232C) for connecting to PC - storing data for further processing or analysis is a snap.
  • It can also connect to the peripheral devices (e.g. receipt printer or modem) for output.
  • Compact flash memory card can be added to some of our models for bigger storage.

How big is the printing area on rewritable card?

  • The thickness of PET Card is 0.25mm.
  • We offer a superior alternative at 0.19mm.
  • The card surface area is 85.6mm x 54mm.
  • The maximum thermal printing area is 55.6mm x 40 mm. 

How many characters can be recorded?

  • The maximum no of characters for printing is 500 (12 x 24 font size each).

How is the resolution? Can it support Chinese characters printing?

  • The resolution is 8 dots/mm or 210 dpi. It can support Chinese and English characters or graphics.

How long does it take to witness the rewrite process?

The steps are as follow:

  1. Reading magnetic strip data
  2. Processing & calculation
  3. Update the magnetic strip data
  4. Erasing the visual data on card
  5. Reprint the new visual data
